A process cartridge detachably mountable to an image forming apparatus for forming an image on a recording material includes a first unit including at least an image-bearing member, a second unit including at least a developing device for developing an electrostatic image formed on the image-bearing member, and a connector for separably connecting the first unit and the second unit with each other, which permits integral mounting and demounting of the first and second units relative to the image forming apparatus. The second unit has a life which substantially equals to the life of the image forming apparatus, and the first unit is replaceable by separation thereof from the second unit outside the image forming apparatus.
