Claim:
An image-forming device comprising: a main casing; a main casing cover attached to the main casing; a process cartridge having a photosensitive body and capable of being mounted in and removed from an image-forming position defined inside the main casing; a cartridge gear disposed on the process cartridge and provided to the photosensitive body; a drive gear disposed on the main casing and capable of engaging with the cartridge gear to transfer a driving force to the cartridge gear; and a restricting portion provided on the main casing and capable of switching between a restricting position and a non-restricting position, the restricting portion at the restricting position restricting the process cartridge from moving out of the image-forming position in a direction opposite a mounting direction when the drive gear engages with the cartridge gear to transfer a driving force to the cartridge gear, and the restricting portion at the non-restricting position canceling the restriction of movement on the process cartridge.
