Title:

IMAGE FORMING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2021/002410

Kind Code:

A1

Abstract:

This image forming apparatus 100 can execute constant voltage control on a voltage applied to a transfer member 8 and execute limiter control for controlling the voltage applied to the transfer member 8 on the basis of a detection result of a current detection unit 21 such that the detection result of the current detection unit 21 is within a predetermined range. The image forming apparatus 100 can execute a first mode in which a toner image is transferred to a recording material P and a second mode in which a plurality of different voltages are applied to the transfer member 8 and a plurality of test toner images are transferred to the recording material P, wherein: when the first mode is executed, a control unit 50, can execute limiter control while the recording material P passes through the transfer unit 8l and when the second mode is executed, the control unit 50 does not perform the limiter control while a region where the plurality of test toner images are transferred passes through the transfer unit N2.
