Abstract
An image forming apparatus is provided in which, by detecting an image formed on a recording medium, at least one of the density and chromaticity of the image can be properly controlled. The image forming apparatus includes an image forming unit for forming a toner image on an image carrier, a transfer unit for transferring the toner image formed by the image forming unit onto a transfer material in a transfer position, a fusing unit for fusing the toner image transferred by the transfer unit on the transfer material, a feed-direction changing unit for changing over a feed direction of the transfer material so that the transfer material having the toner image fused by the fusing unit is reversed and fed to the transfer position, a detecting unit for detecting, in a predetermined detecting position, the toner image fused on the transfer material by the fusing unit, and a control unit for controlling the image forming unit based on result detected by the detecting unit.
