Abstract
When a front cover of a body of a printer is opened, a count value in a system RAM included in a printer body control processor is recorded in a counter in an E.sup.2 PROM included in a process cartridge through a system bus and an input/output port. On the other hand, when the front cover of the printer body is closed, a count value of the E.sup.2 PROM is recorded in the counter in the system RAM. Even in the case where a main switch is turned off, electric power from a receptacle is supplied to each control circuit through a transformer.
