Abstract

An image forming apparatus supporting system includes a first control unit to perform a series of controls relative to the main body that performs the image forming operation; a program storage memory connected to the first control unit via an address bus and a data bus; a non-volatile memory to store maintenance data relative to the main body and an interface circuit that enables the interface between the non-volatile memory and an external device. Further, this system includes a second control unit that controls the main body so that maintenance data can be transmitted from a non-volatile memory to the external device via the interface circuit according to input/output items designated by the external device when the first control unit is not performing the control of the image forming operation in the main body.
