摘要： PROBLEM TO BE SOLVED: To provide a developer replenishment unit recycling method that makes it possible to completely recycle a developer replenishment unit easily without damaging components. SOLUTION: First, a discharging port shutter 5f3 provided on a toner replenishment container 5 is turned to open a toner discharging opening 5f. Then, the toner replenishment container 5 is fixed in an attitude so that the toner discharging opening 5f faces up, a tool 200 for refilling with toner is inserted in a first opening 5f5, and refill toner is poured from the toner discharging opening 5f (as shown by an arrow A in the figure). While the toner is poured, a screw 5a in the toner replenishment container 5 is rotated in a direction reverse to the direction in which toner is supplied to a development device 4. Thus, the poured refill toner is conveyed to the depths of the toner replenishment container 5 (as shown by arrows B, C, and D in the figure). COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To maintain a fixed SB gap by preventing contact or impact of a developing sleeve and a layer thickness regulation member. SOLUTION: The development device which develops a latent image with developer and renders it visible includes: a developing sleeve 4a which holds developer thereon; a regulating blade 4c, disposed with a given amount of space left between the developing sleeve 4a and itself, which regulates the thickness of a layer of the developer held on the sleeve 4a; and a developer sealing member 100 which prevents developer from leaking out of a longitudinal end of the developing sleeve 4a. An elastic member 101 which is brought into contact with the regulating blade 4c is disposed near the regulating blade 4c and on the side of the longitudinal end of the developing sleeve 4a rather than the developer sealing member 100.

摘要： PROBLEM TO BE SOLVED: To provide a grip for enhancing the operability of a process cartridge.
SOLUTION: The grip 70 is fitted to the process cartridge 1 on the front edge side in inserting direction (arrow) into the main body of an electrophotographic image forming apparatus with a rotational supporting point 71 and a sliding part 73 is arranged on the back edge side of the cartridge 1. The grip 70 is molded integrally with hinges 72a, 72b, 72c each having the thickness thinner than that of a base material of the grip. When a gripping part 70b of the grip is lifted up from the state that the grip is housed on the top surface of a frame 1a, the hinges are bent, the part 73 is moved between a pressing member 76 and the frame 1a and the part 70b is separated from the frame 1a so that the grip can be held.

摘要： PROBLEM TO BE SOLVED: To position a process cartridge attachably/detachably mountable to the main assembly of an image forming apparatus in a direction substantially perpendicular to the axial line of a photoreceptor drum. SOLUTION: The photoreceptor drum 7 receives rotational driving force from the body of the apparatus via a coupling hole and a coupling projection while the coupling projection receives drawing force toward the coupling hole by the rotation of a body side gear when the process cartridge B is mounted on the apparatus body. In such a case, the process cartridge B moves in the direction substantially perpendicular to the axial line of the photoreceptor drum 7. Then, the process cartridge has a cartridge side positioning portion (butting portion 13R3) which abuts on a main assembly side positioning member (butting portion 16f) so as to regulate the further movement of the process cartridge.
