摘要： An image forming apparatus includes a developing cartridge and rotatable member having a cartridge mounting portion with an engaging portion engageable with a portion of the cartridge. The cartridge includes a developing roller for developing a latent image formed on an image bearing member. The rotatable member is rotatable for moving the mounting portion between a mounting and demounting position for mounting and demounting the cartridge and another position. The engaging portion is movable between a regulating position, in which disengagement of the cartridge from the mounting portion is suppressed, and a permitting position in which the disengagement of the cartridge from the mounting portion is permitted. When the mounting portion is at the another position, the engaging portion is regulated at the regulating position. When the mounting portion is at the mounting and demounting position, the engaging portion is movable from the regulating position to the permitting position.
