Abstract: An improved image forming apparatus having an endless belt is provided. The apparatus uses an endless belt as a toner image carrier for holding a toner image thereon and transporting the toner image. In one embodiment, rib members are arranged on opposing ends of the endless belt to assist in inhibiting the endless belt from walking relative to a drive roll. A rib guide member is interposed between the rib member and the drive roll, and is rotatable independent of the drive roll. In another embodiment, the toner image is transferred from a photosensitive member to the endless transfer belt and then to a recording medium. Indicia is arranged on an outer perimeter surface of the endless transfer belt indicative of a position of the endless transfer belt, with a sensor used to detect the indicia.

Abstract: Four cooling fans 1 to 4 are provided under a pressure roller along its axial direction in a symmetric manner. The outside cooling fans 1 and 4 are disposed so as to face the non-paper-passing portions of the pressure roller when an A1 size transfer sheet is running with-its longer sides being parallel with the transport direction. The middle cooling fans 2 and 3 are disposed so as to face the non-paper-passing portions of the pressure roller when an A2 size transfer sheet is running with its longer sides being parallel with the transport direction. If the ambient temperature is high, all the cooling fans 1 to 4. are driven. If the ambient temperature is low, only the cooling fans 1 and 4 are driven when an A1-size sheet comes.
