Title: Electrophotographic image forming device and process cartridge
Inventor: YOSHIOKA KIYOHARU
IPC: G03G15/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To correctly load a process cartridge even when an operator incompletely loads it inadvertently by closing an opening/closing member so that the cartridge may be fed to a position where a pull-in means can energize the cartridge to a loading position. SOLUTION: In the case of loading the process cartridge 11 in a device main body 45, a door 21 is opened so as to respectively slide a ground shaft 12 and the rib of a guide member along a guide rail 16. In such a case, the shaft 12 comes in contact with the front side of the projecting part of a pull-in spring 17 and becomes resistance to entering. When the operator stops the loading operation at this position inadvertently and tries to close the door 21, a push-in part 22 abuts on the receiving surface 13 of a cleaning frame body. By moving the door 21 in a closing direction, the part 22 pushes the surface 13 so that the cartridge 11 advances in a loading direction. When the shaft 12 is pushed to a position where it goes over the apex angle of the projecting part of the spring 17, the shaft 12 is pulled in the loading direction by the energizing force of the spring 17.
