ABSTRACT:
An image forming apparatus includes a subunit. The subunit includes a non-volatile RAM which previously stores data items corresponding to ID information used in the manufacturing process of parts constructing the image forming apparatus, ID information of the main body of the image forming apparatus, history information of the parts used at the time of service operation and maintenance information. A support tool is connected to a communication I/F in the manufacturing process and at the time of service operation, and necessary information stored in the non-volatile RAM is read out in response to a readout instruction from the support tool and displayed on the display screen of the support tool. Data corresponding to ID information of the part incorporated in the manufacturing process and data corresponding to service information in the service operation are stored in a preset storage area of the non-volatile RAM.
