ABSTRACT:
An image forming apparatus includes a unit having a first non-volatile memory holding recognition information of the unit and a main body in which the unit is installed in a replaceable manner. The main body has a second non-volatile memory holding a plurality of second recognition information concerning a plurality of units and a plurality of control information corresponding to the plurality of second recognition information. The image forming apparatus is configured such that when a comparison is made between the recognition information held in the first non-volatile memory and the plurality of second recognition information held in the second non-volatile memory and the recognition information held in the first non-volatile memory does not accord with any of the plurality of second recognition information held in the second non-volatile memory, an image forming operation is performed based on selected control information.
