Abstract
A controller controls a voltage to be applied to the transfer member when there is a recording material having a predetermined largest width at a secondary-transfer position, so that a constant-voltage element maintains a predetermined voltage, whereby it is possible to prevent transfer defect due to short of a primary-transfer electric field at a primary-transfer portion when a toner image is secondary-transferred onto the recording material.
