Cartridge and image forming apparatus

A disassembling method for disassembling, from a frame, a bearing member provided in a cartridge detachably mountable to a main assembly of an image forming apparatus, wherein the cartridge include:

• a process member including a shaft acting on an image bearing member;
• a bearing member for supporting the process member;
• a frame including a supporting portion for movably supporting the bearing member;
• wherein the bearing member is movable, by moving the supporting portion, between a first position in which the process member acts on the image bearing member and a second position which is remote from the image bearing member more than the first position,
• an urging member for urging the bearing member from the second position toward the first position;
• a suppressing portion for suppressing dismounting of the bearing member, urged by the urging member, from the supporting portion;
• and
• a dismounting portion for permitting dismounting of said bearing member from the frame at the second position, said disassembling method comprising:
• a step of moving the bearing member supported by the supporting portion to the second position;
• and
• a step of disassembling the bearing member from the frame.
