Abstract:
1. An image forming apparatus, comprising: a plurality of toner-image forming units that receive image data and form electrostatic latent images on image bearing members in accordance with the image data, and form toner images of respective colors by developing the electrostatic latent images; an intermediate transfer member onto which the toner images are transferred; a transfer unit that transfers the toner images of the respective colors onto the intermediate transfer member; a misregistration detector that detects a difference of a transfer position of each of the toner images of the respective colors on the intermediate transfer member when a degree of surface irregularity of a recording medium is greater than or equal to a predetermined threshold, before a toner image, that is to be transferred onto the recording medium, is formed, wherein the controller controls such that when the degree of surface irregularity of the recording medium is greater than or equal to the threshold, the at least one of the transfer pressure and the transfer electric field is smaller than that used when the degree of surface irregularity is smaller than the threshold.
