摘要： An image forming apparatus includes an image bearing member for carrying a toner image; an image forming unit for forming a toner test image on the image bearing member; a transfer material carrying member, for carrying a transfer material, wherein the test toner image is transferred onto a transfer material carried on the transfer material carrying member or onto the transfer material carrying member; and a density detecting unit for detecting a density of the toner test image transferred to the transfer material carrying member. A transfer intensity is smaller when the toner test image for density detection is transferred onto the transfer material carrying member than when the toner test image is transferred onto the transfer material tarried an the transfer material carrying member. The transfer intensity also changes depending on whether the transferred toner test image is the first color toner test image or the second toner test image, and depending on an ambient condition sensor.

The sheet member has an area not fixed to the elastic layer. The transfer medium bearing member is rotated with a potential difference created between the image bearing member and the sheet member before the operation of transferring the images on the image bearing member to the transfer medium born on the sheet member is started.

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.
