PURPOSE:To eliminate a process for exchanging a storing element or initializing operation by arbitrarily selecting whether or not counted information concerning service life of a photosensitive body is to be written to the storing element, and not carrying out writing of the information to the storing element at the time of printing inspection before shipment. CONSTITUTION:The device is provided with EEPROM 25 counting the printed number of pieces as the counted information concerning the service life of the photosensitive body. Furthermore, a dip switch 31 is provided to select from outside whether or not data of the counted number of pieces is written to the EEPROM 25. When printing is carried out by connecting the electric power source in a state where the dip switch 31 is turned OFF, the number of printed pieces within the EEPROM 25 is renewed, and if printing is carried out by connecting the electric power source with the switch in an ON state, control is carried out so that the printed number of pieces within the EEPROM 25 is not renewed. |
