PURPOSE:To provide an image forming device capable of preventing image flowing and obtaining an excellent-quality image by heating a photoreceptive film without keeping a developing device and a cleaning device away from a photoreceptor drum before starting forming an image. CONSTITUTION:A heat roller 35 locally heating the photoreceptive film 22 at high temperature is installed at a position where it is opposed to a main electrostatic charger 24 inside the photoreceptor drum 23. The drum 23 is connected to a controller 33 through a driving device 32, and the speed of the drum 23 is controlled by the controller 33. The rotating speed of the drum 23 before starting forming the image is set lower than that at the time of forming the image, and the film 22 in the vicinity of the charger 24 is heated to 60-100 deg.C by the heat roller 23. The rotating speed of the drum 23 at this time is set so that the temperature at an optional point on the film 22 in the vicinity of the charger 24 may be <=55 deg.C when the point reaches the vicinity of a developing device 26. |
