摘要： PROBLEM TO BE SOLVED: To provide a developing device capable of preventing defective image quality such as void caused by the torque increase of a rotating system without providing a drive source having excessive capacity, thereby developing an image with a satisfactory quality. SOLUTION: When detecting that the drive load current of a motor 25 has reached a predetermined value or above, the developing device 1 operates a switching means 30 such that an idle gear 24 is disengaged from a supply roller gear 23 and a stirring conveyance gear 22. In this state, the rotation of a toner supply roller 12 is stopped and the the value of the drive load current of the motor 25, that is, rotating torque consequently decreases. This prevents a developing roller 5 rotated by the motor 25 from causing an abnormal operation such as gear skipping of the developing roller gear 21. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a development apparatus for easily preventing a leakage of toner from between a front seal plate and a side seal. SOLUTION: The development apparatus keeps both side ends (parts overlapped on the side seal 27) in the front seal plate 23 fixed on a both-side seal 27 by adhesion. In other words, a gap between a both-side part A1 of an opening part A in a toner tank 49 and a return edge A2, and a developing roller is integrally sealed by the side seal 27 and the front seal plate 23 fixed mutually. Thus, the development apparatus can prevent the side seal 27 and the front seal plate 23 from generating a gap (the side seal 27 and the front seal plate 23 from being separated) by vibration due to external force and secular change.

摘要： PROBLEM TO BE SOLVED: To suppress detection error in a state detection mechanism detecting a state of a replacement part. SOLUTION: The state detection mechanism contains a mover 16, a spring member 21, an edge part 20e and a stopper member 20g. The spring member 21 varies the position of the mover 16 from a first specified position to a second specified position by having a recovering force work in a direction D for the mover 16 installed in the first specified position. The edge part 20e restricts the variation in positions by being abutted to a projecting member 16d formed on the mover 16 installed in the first specified position. The stopper member 20g is abutted to the projecting member 16d formed on the mover 16 installed in the first specified position and restricts the rotation of the mover 16 with the direction D as an axis. Here, when torque is transmitted from a shaft body 15 to the mover 16, the mover 16 is rotated with the direction D as the axis, the projecting member 16d and the stopper member 20g are abutted, load is applied by the torque to the abutting place and the projecting member 16d is destroyed by the load.
