IPC: G03G15/00
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent image density and image quality from being fluctuated caused by the rise of temperature in the midst of the action of a device, especially, constituted so that plural developing units are fixedly arranged by disposing a surface-like heating body near the forming part of an electrostatic latent image as for an image forming device provided with an endless belt-like photoreceptor. SOLUTION: The endless belt-like photoreceptor 1 is laid extending over a driving roller 21 and driven rollers 22 and 23 used also as the tension rollers and constituted by forming a photoreceptor layer 12 at the front surface of a film 11. Then, the layer 12 of the traveling photoreceptor 1 is uniformly electrified by a primary electrifier 4 and an image signal 5 is projected on the electrified surface so as to form the electrostatic latent image. Next, when this latent image arrives at a developing part where a developing device 6 is arranged, it becomes a toner image because toner is supplied from the developing device 6. Besides, when the toner image arrives at the position of an endless belt-like intermediate transfer body 7, it is transferred on the transfer body 7.  In the device constituted in such a way, the surface-like heating body is arranged so as to be close to the photoreceptor 1.
