Abstract:
1. An image forming apparatus for forming an image on a recording material, wherein a cartridge is detachably mountable to said image forming apparatus, said image forming apparatus comprising: a first movable member movable between a projection position in which said first movable member is in an insertion path of a contact portion provided on said cartridge when said cartridge is mounted to a main assembly of said image forming apparatus, and a retracted position in which said first movable member is retracted from the insertion path, wherein said first movable member moves from the projection position to the retracted position by being contacted by the contact portion; and a second movable member movable between an open position for permitting said cartridge toward downstream with respect to an inserting direction in which said cartridge is mounted to said main assembly and a blocking position for preventing said cartridge from moving toward the downstream by contacting said contact portion, said second movable member being interrelated with said first movable member so that when said first movable member is in the projection position, said second movable member takes the open position, and when said first movable member is in the retracted position, said second movable member takes the blocking position, wherein in the process of mounting said cartridge to said main assembly, said contact portion passes said first movable member in the inserting direction, and said first movable member moves from the retracted position to the projection position, and then said second movable member moves from the blocking position to the open position, and said contact portion passes said second movable member in the inserting direction.
