<P>PROBLEM TO BE SOLVED: To improve productivity by shortening time required from the completion of primary transfer of a toner image from a photoreceptor to an intermediate transfer body up to the start of secondary transfer of a toner image from the intermediate transfer body to a sheet. <P>SOLUTION: When a sheet onto which a toner image is secondarily transferred from the intermediate transfer body 205 is a prescribed sheet, the rotation speed of the intermediate transfer body 205 is changed from a first speed to a second speed after the primary transfer of a toner image from a photosensitive drum 202 to the intermediate transfer body 205, and moreover, whether the speed of the intermediate transfer body 205 is to be changed within one rotation in which the primary transfer is carried out or within one rotation subsequent to that rotation in which the primary transfer is carried out is determined in accordance with an image formation mode. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
