Abstract
An image forming apparatus, which carries out constant-voltage control of a voltage applied to a transfer memberand is capable of executing limiter control for controlling the voltage applied to the transfer memberbased on a detection result of a current detecting portionso that the detection result falls within a predetermined range, is capable of executing a first mode in which a toner image is transferred onto a recording material P and a second mode in which a plurality of test toner images are transferred onto the recording material P by applying a plurality of different voltages to the transfer member, and a controlleris capable of carrying out the limiter control while the recording material P passes through the transfer portionin executing the first mode and does not carry out the limiter control while an area onto which the plurality of test images are transferred passes through a transfer portion Nin executing the second mode.
