An image bearing member utilized in an image forming apparatus includes a cylindrical member on which an image is formed on a peripheral surface thereof. An image bearing member further includes a filling-up member which suppresses vibration of the cylindrical member by being inserted into an inner part of the cylindrical member, and an anaerobic adhesive which adheres and fixes an outer peripheral surface of the filling-up member to an inner peripheral surface of the cylindrical member by osmosing into a clearance formed between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the filling-up member. The anaerobic adhesive is placed inside of an end face of at least one side of the outer peripheral surface of the filling-up member, and an adhesion width is formed wherein the anaerobic adhesive is spread around an entire periphery of the outer peripheral surface of the filling-up member from an end face of the filling-up member. The adhesive can be hardened by use of ultraviolet rays or a lid. Furthermore, gas can be sealed in the inner part of the cylindrical member. A method for manufacturing an image bearing member for an image forming apparatus includes vertically positioning a filling-up member inside a cylindrical member, injecting an anaerobic adhesive between the filling-up member and the cylindrical member, and hardening the anaerobic adhesive after the anaerobic adhesive has osmosed into the clearance between the cylindrical member and the filling-up member.
