Abstract
A process cartridge detachably mountable to a main body of an electrophotographic image forming apparatus includes an electrophotographic photosensitive member, a process device acting on the photosensitive member, a cartridge frame having a grip portion to be gripped when the process cartridge is mounted to and dismounted from the main body of the image forming apparatus, and first and second concave portions provided on the cartridge frame at one side and other side of the grip portion in a longitudinal direction of the cartridge frame and being concave toward the interior of the process cartridge.
Claims18
A process cartridge detachably mountable to a main body of an electrophotographic image forming apparatus, comprising:
- (a) an electrophotographic photosensitive member;
- (b) process means acting on said electrophotographic photosensitive member;
- (c) a cartridge frame;
- (d) a grip portion to be gripped when the process cartridge is mounted to and dismounted from the main body of the electrophotographic image forming apparatus;
- (e) a first concave portion provided on said cartridge frame at one side of said grip portion in a longitudinal direction of said cartridge frame and being concave toward the interior of the process cartridge;
- and
- (f) a second concave portion provided on said cartridge frame at the other side of said grip portion opposite to said one side in the longitudinal direction of said cartridge frame and being concave toward the interior of the process cartridge.
A process cartridge detachably mountable to an electrophotographic image forming apparatus having an open/close cover, and a first convex portion and a second convex portion formed on an inner surface of said cover, said process cartridge comprising:
- (a) an electrophotographic photosensitive member;
- (b) process means acting on said electrophotographic photosensitive member;
- (c) a cartridge frame;
- (d) a grip portion to be gripped when the process cartridge is mounted to and dismounted from a main body of the electrophotographic image forming apparatus;
- (e) a first concave portion provided on said cartridge frame at one side of said grip portion in a longitudinal direction of said cartridge frame and being concave toward the interior of the process cartridge, said first concave portion being inserted into said first convex portion when said cover is closed after the process cartridge is mounted to the main body of the image forming apparatus by gripping said grip portion;
- and
- (f) a second concave portion provided on said cartridge frame at the other side of said grip portion opposite to said one side in the longitudinal direction of said cartridge frame and being concave toward the interior of the process cartridge, said second concave portion being inserted into said second convex portion when said cover is closed after the process cartridge is mounted to the main body of the image forming apparatus by gripping said grip portion.
An image forming apparatus on which a process cartridge is detachably mounted, comprising:
- (a) mount means for mounting a process cartridge including an electrophotographic photosensitive member, process means acting on said electrophotographic photosensitive member, a cartridge frame, a grip portion to be gripped when the process cartridge is mounted to and dismounted from a main body of said image forming apparatus, a first concave portion provided on said cartridge frame at one side of said grip portion in a longitudinal direction of said cartridge frame and being concave toward the interior of the process cartridge, and a second concave portion provided on said cartridge frame at the other side of said grip portion opposite to said one side in the longitudinal direction of said cartridge frame and being concave toward the interior of the process cartridge;
- and
- (b) an open/close cover having a first convex portion and a second convex portion on an inner surface thereof, wherein upon mounting said process cartridge on the main body by said mount means, said grip portion is gripped after said cover is opened and upon closing said cover the first and second convex portions are respectively inserted into the first and second concave portions.
