Elektrofotografisches Druck- und/oder Kopiergerät

摘要

An electrophotographic recording apparatus in which a thin endless metal belt having a photoconductive photosensitive layer on an outer circumferential surface is provided around a drive roller and an integrated heating and cooling unit, and rotated by the drive roller. A latent electrostatic image forming device (a corona charger and an exposing unit) is disposed adjacent to the outer circumferential surface of the metal belt that is near the drive roller, and a developing device is disposed downstream from the latent electrostatic image forming device adjacent the heating and cooling unit, so that a toner image formed on the metal belt by both devices is transferred and fixed while sequentially brought into pressure contact with a member to which to transfer the toner image. In another embodiment a multi-color electrophotographic recording apparatus is provided in which multi-color toner images are formed on the metal belt using at least two pairs of image forming and developing devices, each pair including a latent electrostatic image forming device and a developing device as in the above-mentioned electrophotographic recording apparatus. The multi-color toner images are then transferred to and fixed on the member by the integrated heating and cooling unit. The integrated heating and cooling unit includes a cooling member, a heater embedded in the cooling member and an insulating member interposed between the heater and cooling member.
