Abstract
A process unit includes a unit frame detachable from a main body frame, a plurality of development cartridges mounted so as to be mutually independently attachable and detachable with respect to the unit frame, and a lock mechanism. The lock mechanism has a lock member that restrains movement of the unit frame by being held at a first position at which the lock member is engageable with the main body frame. The lock member is caused, by all the development cartridges being detached from the unit frame, to shift from the first position to a second position at which the lock member does not engage with the main body frame.
