Abstract:
1. An image forming apparatus, comprising: a transferring belt where a color image is formed; a conveyance belt configured to transfer a recording medium where a monochrome image is transferred; a velocity difference detecting part configured to detect a velocity difference between the transferring belt and the conveyance belt; a determining part configured to determine whether the velocity difference detected by the velocity difference detecting part is equal to or greater than a designated value; a velocity adjusting part configured to adjust the velocity difference so that the velocity difference becomes lower than the designated value in a case where the velocity difference is determined to be the designated value or more by the determining part; and a color correcting part configured to correct a shift of colors between the color image and the monochrome image by using the transferring belt and the conveyance belt whose velocities are adjusted by the velocity adjusting part.
