Abstract:
An image forming apparatus is provided with a cylinder for carrying developing agent, and with a flange fitted into an end portion of the cylinder for supporting the cylinder. A fitting portion of the flange has a diameter larger than an inner diameter of the cylinder. The flange is mounted to the cylinder by press-fitting and has a guide smaller than the inner diameter of the cylinder at an end of the fitting portion for guiding the fitting. A spacer is located at a more central side of the cylinder than the fitting portion of the flange press-fitted into the cylinder.
