ABSTRACT:
An image forming apparatus includes a volatile memory configured to temporarily store usage information of the image forming apparatus, and a non-volatile memory configured to finally store the usage information. An access control device is provided to access the non-volatile memory and output at least an address, data, and a control signal thereto as private use signals independent from a control of the CPU. The access control device may copy the usage information of the non-volatile memory to the volatile memory before image formation is started, and periodically update the non-volatile memory with new usage information temporarily stored in the volatile memory during the image formation.
