A process cartridge includes a rotatable rotary member having a plurality of bearing attachment portions to which bearings are attachable. The plurality of bearing attachment portions are provided on the rotary member with different diameters. A method of reusing a rotation member that is supported at one of a plurality of coaxial rotation surfaces having different diameters includes detaching one of a plurality of bearing members that supports the rotation member at the one of the plurality of coaxial rotation surfaces. Another of the plurality of bearing members is then attached at a corresponding other of the plurality of coaxial rotation surfaces that has a different diameter than the one of the plurality of coaxial rotation surfaces.
A method of reusing a rotation member used in an image forming apparatus, wherein the rotation member is supported at one of a plurality of coaxial rotation surfaces, each of which has a different diameter and is shifted axially from one another, by a corresponding support surface of one of a plurality of bearing members, comprising the steps of:
A method of reusing a developing sleeve for use in an image forming apparatus for supplying a toner to a photosensitive member to develop a latent image formed thereon, wherein the developing sleeve is supported at one of a plurality of coaxial rotation surfaces, each of which has a different diameter and is shifted axially from one another, by a corresponding support surface of one of a plurality of bearing members, said method comprising the steps of:
