ABSTRACT:
A laser printer is configured to move a pinch roller, provided to a main body casing and operating in a position in which the pinch roller obstructs attachment/detachment of a process cartridge, to a position in which the pinch roller does not obstruct attachment/detachment of the process cartridge. Such a configuration can reduce the number of components of the process cartridge compared with the case of incorporating the pinch roller in the process cartridge. In addition, the configuration can reduce the size of the laser printer since it is unnecessary to attach/detach the process cartridge so as to avoid the pinch roller.
