Abstract
Disclosed is an image forming apparatus including a body housing in which an opening is formed for providing removal/mounting access of a removable cartridge; a door member for selectively closing the opening. The removable cartridge includes a cartridge status chip in which predetermined information relating to the removable cartridge is recorded. The door member of the image forming apparatus and the removable cartridge may each be provided with respective contact terminal or terminals that engage when the door member is closed with the removable cartridge received in the body housing of the image forming apparatus. The controller of the image forming apparatus uses the electrical continuity information of the contact terminal or terminals in order to determine the closure status of the door member and to control the operation of the image forming apparatus accordingly.
