<p><P>PROBLEM TO BE SOLVED: To suppress color shift by reducing frictional force among a plurality of photoreceptors and a belt and making the positions of toner images on all the photoreceptors align with one another. <P>SOLUTION: Reduction information to reduce the speed of the belt so that the moving amount of the belt at the time of reducing the speed from a normal one to zero in speed becomes larger than the moving amount of the photoreceptor drum at the time of reducing the speed from the normal one to zero in speed in accordance with the moving amount difference obtained by subtracting the predetermined moving amount of the belt at the time of accelerating the speed from zero to the normal speed from the prescribed moving amount of the photoreceptor drum at the time of accelerating the speed from zero as reduction speed to the normal speed is stored in a one-step acceleration/reduction table 563a. A belt motor control part 55 controls the speed of a belt motor 24 on the basis of the reduction information stored in the one-step acceleration/reduction table 563a. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
