Abstract
A cartridge mountable to a printer, said printer including a coupling guide contactable to a coupling of the cartridge to guide the coupling member. A case of the cartridge is provided with a hole for exposing a free end portion of the coupling to an outside of the cartridge, and a retracted portion provided in downstream of the hole with respect to the mounting direction of the cartridge. When the cartridge is mounted to a main assembly of the printer, the coupling guide enters the retracted portion from which the coupling member has retracted.
