Patent ID: 7093919

Claim:
An image formation device, comprising: a new process cartridge detecting unit that detects when a new process cartridge is set; an initialization unit that performs an initialization of the set new process cartridge when the new process cartridge detecting unit detects the new process cartridge; an initialization flag storing unit that stores an initialization flag that indicates an initialization status of the new process cartridge; an initialization flag setting unit that controls and sets the initialization flag in the initialization flag storing unit; and an initialization history storage unit that stores a progress history of the initialization of the new process cartridge, the progress history indicating completion or non-completion of sequential initialization operations, wherein the initialization flag setting unit sets the initialization flag to indicate non-initialization before the new process cartridge detecting unit detects the new process cartridge, when the initialization of the new process cartridge is interrupted, the initialization unit restarts the initialization of the new process cartridge, based on the progress history stored in the initialization history storage unit, at a next initialization operation following a last completed sequential initialization operation.
