    摘要： An image forming apparatus includes a plurality of movable image carriers, a movable intermediate transfer body, and a contacting member separably contacting to the intermediate transfer body at a contacting position. A position for transfer between a first image carrier and the intermediate transfer body defines a first transfer position. A position for transfer between a second image carrier and the intermediate transfer body defines a second transfer position. A toner image formed on said intermediate transfer body is again transferred onto a transfer material after passing through said first transfer position and said second transfer position. The latent image formation on the first image carrier is done at a time different from a contacting operation of the contacting member.

    摘要： An image forming apparatus is provided with photosensitive drums for forming latent images by irradiation of light reflected by a polygon mirror and a fixing device for fixing toner images corresponding to the latent images on a sheet material. Deterioration of an image to be formed is prevented if reflective surfaces of a reflective polyhedron are thinned out in reducing a process speed of image formation. This apparatus is further provided with a control unit for, if the number of surfaces of the polygon mirror is m (where m is an integer of three or more), performing a control for selecting n such that m/(n+1) is not an integer as a relation between m and n and performing a control for making n surfaces unused as a reflective surface of light among continuous n+1 surfaces of the reflective polyhedron in decelerating the image forming process.
