A plurality of sheets of photofixed-recording medium are stacked on top of each other and stored in a cartridge. An EEPROM is attached to the cartridge. The EEPROM is connecting to a memory connection section. A central processing unit is connected to the memory connecting section. The central processing unit can write information to the EEPROM of the cartridge or read information therefrom. Access to EEPROM can be correctly obtained only when the cartridge is properly inserted into a printing apparatus.

To keep a toner ( ) deposited on a transportation belt ( ) from contact with a printhead ( ) and prevent the clogging of toner passage holes ( ) of the printhead ( ), the toner ( ) on a toner holding member ( ) is ejected toward the transportation belt ( ) through the toner passage holes ( ) after the movement of the transportation belt ( ) is initiated such that the cleaning of the toner passage holes ( ) is initiated.

Image forming method and image forming apparatus

A cartridge comprises a shutter for opening and closing an opening portion formed on a ceiling plate of an upper side member. The shutter slides on an outer surface of the ceiling plate by attaching and detaching the cartridge. Lifter projections are projected on a back portion of a lifter provided in the cartridge. The lifter projections are projected to an outer section through an opening portion formed on a bottom plate of a lower side member. If the cartridge is put on the plane, the lifter projections are pressed to an interior, so that the lifter is pushed up. Thereby, a recording paper is pressed onto the back surface of the ceiling plate. As a result, a space of the cartridge is lessened, the flow of air from the outer section is reduced, and a variation in internal moisture is controlled.

In a thermal printer for thermo-sensitive recording, a plurality of heating resistors are electrically divided into N units each having M heating resistors, and N driver circuits, N latch circuits and N shift registers which are interconnected in tandem are respectively provided in association with the N units of M heating resistors. Dot data signals and associated hysteresis correction signals are collectively applied to the shift registers so that a pulse for print data and a pulse for hysteresis correction data can be applied continuously for printing.

The present invention relates to a ribbon feed mechanism for use in a heat transfer printer. The ribbon feed mechanism includes first, second, and third ribbon feed components fitted on a shaft, a friction plate mounted between the first and second ribbon feed components, a spring mounted between the second and third ribbon feed components, a cylinder which is in contact with the third ribbon feed component at one end thereof, and a ribbon feed presser for pressing the other end of the cylinder toward the third ribbon feed component. The rotational torque is always kept constant, and therefore no unmatching of colors occurs when the mechanism is applied to a printer.
