An engine control part starts data transmission to a nonvolatile memory of a process cartridge. An opening/closing sensor continues to detect an opening or closing state of an upper door open and closed for attaching or detaching the process cartridge until the engine control part confirms that the data transmission is finished. If such a state that the door is open is detected, the engine control part halts the data transmission, and temporarily stores the data currently transmitted in a memory thereof. After that, when the upper door is closed and mounting of the process cartridge is confirmed, the engine control part re-executes the data transmission so that the data temporarily stored in the memory thereof will be re-transmitted.
