An electrophotographic apparatus is provided in which toner stick hardly occurs by improving the cooling effect on the strip of paper sheets after they are heat-fixed. This electrophotographic apparatus includes a fixing unit for heating toner transferred on a continuous strip of paper sheets and fixing the toner, and a folding unit for supplying a folding force to the continuous strip of paper sheets. A conveyer unit is arranged in the back stage of the electrophotographic apparatus for transferring the continuous strip of paper sheets, received from folding unit, in the horizontal direction.

A toner supply control system of the electrophotographic apparatus which includes a developing unit 3 for developing with a developer composed of toner and carrier; a toner hopper 4 for storing the toner; a toner empty sensor 7 for detecting the remainder of toner in the toner hopper 4; and a toner supply drive unit 5 for conveying toner from the outside of the apparatus into the toner hopper 4. Toner is conveyed from the outside into the toner hopper 4 by driving the toner supply drive unit 5 over a predetermined period of time without stopping the operation of the electrophotographic apparatus when the toner empty sensor 7 detects over a predetermined period of time that the remainder of toner in the toner hopper 4 is small. Then the existence of an output signal outputted from the toner empty sensor 7 indicating that the remainder of toner is small is detected, and a previous signal of toner shortage is output while the developing operation of the electrophotographic apparatus is being maintained in the case of existence of the output signal, and the shortage of toner is reported to an operator in accordance with the previous signal of toner shortage.

A film loading method of an image forming apparatus, includes: loading an endless film which was stored in a container box, using at least two support members, to a film frame of the image forming apparatus, wherein the film is supported by the support members in a different form with respect to a condition of the film when loaded and fitted to the film frame. The support members are initially stored in the container box and serve as a packaging member for use in transporting and storing the film. The support members are attached to respective portions of the film frame and guide the film to be loaded and fitted onto the film frame. The film frame includes holding rollers, and the support members are attached to the respective portions of the film frame, coaxially with the holding rollers.

A heating belt is laid along a conveying path for a recording medium moved after development, a halogen lamp is incorporated in a belt drive roller for driving the heating belt so as to heat the heating belt by heat generated by the halogen lamp, and accordingly, the heating belt whose temperature is controlled at a predetermined temperature heats the recording sheet. With this arrangement, the conveying speed of the recording sheet and the moving speed of the heating belt are set to be equal to each other. Alternatively, the heating belt may itself generate heat.
