Abstract

PURPOSE:To reduce wear generated by a difference in peripheral speeds by providing a transfer sheet conveying means and a transfer means against an image forming parts so that they can make contact with and apart from said parts and slightly separating the conveying means from the image forming parts when no image is formed. CONSTITUTION:The image forming parts 3, 5 and 6 for color images are arranged inside a device 2, a conveying belt 17 is stretched to a frame 13 below the device, and transfer electrifiers 29, 39 and 49 are attached, of which a conveying unit 70 is composed. When image forming actions start or stop, a cam 66 is turned by means of a cam motor, and the conveying unit 70 is put below and away from the position of the image forming parts together with a lifter frame 67. Therefore contact wear, which is generated by a difference in peripheral speeds of the conveying means and the image forming parts and continues until rotation becomes stable can be minimized.
