摘要： PROBLEM TO BE SOLVED: To provide a method for reproducing a process cartridge by which the process cartridge losing its commercial value as a process cartridge as the result of consuming a developer to the degree of being not capable of forming an image of a quality satisfying a user can be made merchandise again. SOLUTION: A pin combining a drum unit and a developing unit is pulled out and separated by working a drum frame 11d. A photoreceptor drum 7 is detached from the drum unit and the drum frame is cleaned to reuse it or to fit a new photoreceptor drum. A developing roller 10d is detached from the developing unit. A developing blade 10e is detached to replenish a toner housing part 10a with toner from a toner replenishing port, and a the toner housing part and a toner feeding opening 10k to the developing roller are toner- sealed again. Then, the developing blade and the developing roller are fitted to make the developing unit, and the reproduced drum unit and developing units are combined.

摘要： PROBLEM TO BE SOLVED: To provide an end member capable of easily performing the filling work of a developer to a developer housing part by mounting an end member having a removable grip member to be gripped in opening of a seal member on one longitudinal end part of a developer housing part so as to cover a developer filling port. SOLUTION: A grip member 21b is removably provided from an end member 21. Namely, the thickness of a connecting part 21c to be connected to the end member 21 is particularly reduced so that it is separable by bending. The end part of a tear tape is adhered or welded to the grip member 21b. The end part of the tear tape protruded out of a process cartridge and the root part side of the grip member 21b are separated from the end member 21 and tore off, and the protruding part 21K of the grip member 21b is pulled by the finger of an operator, whereby the tear tape is pulled out to tear a cover film, and the toner in a toner developing frame is sent from a toner chamber to a developing chamber through an opened toner passing port.

摘要： PROBLEM TO BE SOLVED: To prevent toner particles from being bulky by transmitting driving force from a driving member to a drive transmitting member through an engagement part engaged with an inclined surface of a projecting part provided in the direction intersecting the rotating direction of the driving member. SOLUTION: An engagement surface of a shaft coupling part 9s1 of a toner feed gear 9s is allowed to abut to the engagement surface of a coupling member 11e of a transmitting shaft 41, whereby the rotary driving force T1 is transmitted from the toner feed gear 9s to the transmitting shaft 41. When the rotary driving force T1 is transmitted from the engagement surface of the toner feed gear 9s to the engagement surface of the transmitting shaft 41, thrust force in the direction of forcing the transmitting shaft 41 in a toner container 11A is generated at the respective engagement surfaces of the toner feed gear 9s and the transmitting shaft 41, so that a stopper part 41b of the transmitting shaft 41 runs against the thrust bearing surface 11u of a bearing house 11s of the toner container 11A. Thus, a clearance L between a shaft stop ring 44 for stopping the transmitting shaft 41 and the inner wall of a toner frame 11 can be secured, so that the shaft stop ring 44 is rotated in contact with the inner wall of the toner frame 11 with toner interposed between them.

摘要： PROBLEM TO BE SOLVED: To prevent extraction of a drum flange, a gear, or the like and idle- running of them against a cylinder even when they are thermally contracted or expanded due to temperature change. SOLUTION: A cylindrical member (drum, or the like) 7 and an engagement member (flange gear, or the like) 16 are press fit and fixed in an engagement part 16b of the cylindrical member 7 and the engagement member 16 by molding a material having the same thermal expansion coefficient (thermal contraction rate) as the cylindrical member 7. A molding method is two color molding or insert molding, and knurling is further applied on the engagement part of the cylindrical member and the engagement member.

摘要： PURPOSE:To prevent the buckling of a sealing member on a sealing adhesive surface and to simplify resealing even when a contact area is small by forming notches parallel in a longitudinal direction with nearly the same interval as the width of a slit on a flexible sheet. CONSTITUTION:The resealing member 26 is constituted of the flexible sheet 26a, a sticky part 26b provided at a sealing part 26a1, and a peeling sheet 26c covering the sticky part 26b. The flexible sheet 26a is set so that relation between the length L1 of the sealing part 26a1 in entire length L and the length L2 of a pull part 26a2 may be L2>L1. Dimension in a width direction is set so that the width W of the sealing part 26a1 may be longer than the width of the slit 27 between a toner container and a developing frame. Two notches 26d are formed in parallel with the longitudinal direction with the same interval W1 as the width of the slit 27 on the sealing part 26a1. Furthermore, the width W2 of the pull part 26b is set to shorter than the width of the slit 27.

摘要： PURPOSE:To provide the reproducing method of a process cartridge and the cartridge, not having a fear that the leakage of toner does not occur at the time of reusing. CONSTITUTION:In the reproduction of the process cartridge, a new toner developing frame constituted in such a manner that a new photoreceptor drum, a new toner frame 31 and a developing frame 32 are engaged in a state where a new toner seal for preventing the leakage of the toner housed in a toner housing part is interposed between both frames is prepared and a reused drum frame is prepared as well. Then, processes for housing the toner in the toner housing part of the new toner frame 31, attaching a developing roller 33 to the new developing frame 32 and the photoreceptor drum to the reused drum frame and turnably engaging the new toner developing frame 32 with the reused drum frame are provided.

摘要： PROBLEM TO BE SOLVED: To make an image forming device and a processing cartridge small in size by shortening a size of a photosensitive drum in a longitudinal direction. SOLUTION: In this device, a hole 7b is born on a circumference of a cylinder 7d edge part of the photosensitive drum 7 and a gear flange 2 is formed outserted so that the hole 7b is covered. Thus, deformation of a cylinder 7d is not caused by caulking and since a space roll of a developing roll can be received at the edge part of the drum, the whole length of the drum can be shortened.

摘要： PROBLEM TO BE SOLVED: To smooth the circulation of developer by dividing a developing device main body to a developer storing chamber and a rotatable developing processing chamber where the developer is carried and shifted and arranging a developer remaining amount detecting body in the developer storing chamber. SOLUTION: Relating to this developing device 10; a toner chamber 10a and the developing processing chamber 10b are formed by connecting a toner developing frame body 12 and a toner developing wall member 13. An antenna wire 105 being the developer remaining amount detecting body arranged inside the toner chamber 10a is fixed on the toner developing frame body 12 so as to be nearly in parallel with a developing roller 10c. Since the antenna wire 105 arranged in the toner chamber 10a detects the remaining amount of toner in the developing device 10 based on the change of electrostatic capacity between the developing roller 10c and the antenna wire 105, the remaining amount of the toner is excellently detected without hindering the circulation of the toner in the developing processing chamber 10b along with the miniaturization of the developing device 10.
