Abstract
A mountable unit set usable with an electrophotographic-image-forming apparatus includes a cartridge and an attachment. A cartridge includes a photosensitive drum and a coupling member for receiving a driving force for rotating the photosensitive drum, from a driving shaft. An attachment includes a cylindrical portion for being mounted to a periphery of the driving shaft to suppress tilting of the driving shaft. Tilting of a driving-force transmitting member is suppressed.

A mountable unit set usable with an electrophotographic image forming apparatus, the mountable unit set comprising:
- (1) a cartridge detachably mountable to an apparatus main assembly of the electrophotographic image forming apparatus, the cartridge including a photosensitive drum and a coupling member for receiving a driving force for rotating the photosensitive drum from a driving shaft provided in the apparatus main assembly, and
- (2) an attachment mountable to the apparatus main assembly and including a cylindrical portion configured to be mounted around the driving shaft and configured to suppress tilting of the driving shaft.
An attachment detachably mountable to an apparatus main assembly of an electrophotographic image forming apparatus, the attachment comprising:
- a cylindrical portion mountable to a driving shaft provided in the main assembly, the cylindrical portion being configured to suppress inclination of the driving shaft.
A mountable unit set usable with an electrophotographic image forming apparatus, the mountable unit set comprising:
- (1) a cartridge including a photosensitive drum and a coupling member for receiving a driving force for rotating the photosensitive drum;
- and
- (2) an attachment including a cylindrical portion having, with opposite ends of the cylindrical portion in an axial direction being open.
An attachment usable with an electrophotographic image forming apparatus, the attachment comprising:
- a cylindrical portion having opposite ends that are open in an axial direction, and
- a grip portion extending from an outer periphery of the cylindrical portion in a radial direction of the cylindrical portion.
A cartridge mounting method comprising:
- a step of suppressing a tilting of a driving shaft by mounting an attachment to the driving shaft provided in a main assembly of an electrophotographic image forming apparatus, and
- a step of mounting a cartridge to the main assembly of the apparatus to which the attachment has been mounted.
