Method for manufacturing image bearing unit and method for manufacturing cartridge

A manufacturing method for manufacturing an image bearing unit from a material unit,

• the material unit including:
• an image bearing member;
• a frame including a first engaged portion, the frame including a projecting portion projecting toward an outer side of the frame with respect to an axis direction of the image bearing member;
• a supporting member including a fixed portion fixed to the frame, the supporting member including a bearing portion that supports the image bearing member, a through-hole, a second engaged portion opposed to the first engaged portion, and a cover portion that covers at least a part of the projecting portion penetrating the through-hole, the cover portion including a contact portion;
• and
• a developing unit including an engaging portion, the engaging portion engaging with the first engaged portion and the second engaged portion such that the developing unit being swingably coupled to the frame,
• wherein the contact portion is configured to come into contact with the projecting portion when the supporting member is deformed
• to allow the second engaged portion to be detached from the engaging portion in a state in which the fixed portion is fixed to the frame,
• the manufacturing method comprising:
• a removing step of removing at least a part of the contact portion from the supporting member;
• a deforming step of deforming the supporting member to allow the second engaged portion to be detached from the engaging portion in the state in which the fixed portion is fixed to the frame;
• and
• a separating step of detaching the engaging portion from the first engaged portion and separating the developing unit from the frame.
