Problems solved by technology
[0004] The way that the above-mentioned force-applying part applies force to the force-receiving part to force the toner bin to separate from the waste toner bin can achieve the purpose that the photosensitive element will not be polluted. However, since the force-receiving part is fixedly installed in the toner bin, in order to ensure that the The force part can be combined with the force application part, and the force receiving part is set to be relatively protruding. When the process box falls or is bumped during transportation, the force receiving part may be broken, thus causing the developing member to be separated from the The photosensitive element cannot be separated, causing the photosensitive element to be contaminated

Embodiment Construction
[0022] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. First, define the length direction of the process cartridge 1 as longitudinal X, the width direction as transverse Y, and the installation direction as vertical Z.
[0023] [processing box]
[0024] figure 1 is a perspective view of a process cartridge according to the present invention; figure 2 It is an exploded view of the process cartridge according to the present invention.
[0025] Process cartridge 1 comprises a first unit 2, a second unit 3 and a compression spring 7 between the first unit 2 and the second unit 3, the second unit 3 is rotatable with respect to the first unit, and the compression spring 7 is used to provide forcing The forcing force of the second unit 3 in contact with the first unit 2. Further, the process box 1 also includes a first end cover 4 and a second end cover 5 located at two longitudinal ends respectively, and the ...

The invention relates to a processing box with a movable part. The processing box can be detachably installed on an electrophotographic image forming device. The processing box comprises a first unit,a second unit, and a first rotating piece and a second rotating piece which are rotatably mounted in the first unit and the second unit respectively. The processing box further comprises a movable piece capable of moving between an initial position and a terminal position. When the movable piece is located at the initial position, the first rotating piece makes contact with the second rotating piece. When the movable piece is located at the terminal position, the first rotating piece and the second rotating piece are separated from each other. Before the first rotating piece and the second rotating piece are separated from each other, the contact point of the movable piece and the second rotating piece is P. After the first rotating piece and the second rotating piece are separated from each other, the contact point of the movable piece and the second rotating piece is Q. Along the installation direction of the processing box, the point P is located on the upstream of the point Q. Even if the processing box falls off or collides with the point Q, due to the fact that the movable piece has a certain activity amount, the probability that the movable piece is broken can be greatly reduced.
Description
technical field [0001] The present invention relates to the field of electrophotographic image forming, and more particularly to a process cartridge detachably mounted to an electrophotographic image forming apparatus. Background technique [0002] Currently, the process box includes a powder bin and a waste toner bin combined with each other. The powder bin is used to accommodate the toner required for development. The developing part for carrying the carbon powder is rotatably installed in the powder bin. It is used to accommodate the waste toner produced by development, and the photosensitive element used to form the electrostatic latent image is rotatably installed in the waste toner bin. The electrostatic latent image formed on the surface is developed. [0003] When the process cartridge does not need to work, in order to prevent the surface of the developing member from being deformed or the surface of the photosensitive member from being polluted due to long-term co...
