Abstract
An image forming apparatus wherein an unfixed image is formed on a recording material at an unfixed image forming station, such as an image transfer station or a station for developing an electrostatic latent image. The unfixed image is fixed by a fixing device including a couple of fixing rollers, one of which is substantially frustoconical. The present invention is effective to avoid the possible disturbance to the image caused by the frustoconical shape of the roller. The preferable arrangement is such that the distance between the image forming station and the nip formed between the rollers is shorter than the length of the recording material, and that the nip is non-parallel with respect to the leading edge of the on-coming recording material. Further, the small diameter side of the conical roller receives the leading edge of the sheet earlier than the large diameter side of the frustoconical roller.
