Abstract
In an image forming machine ( ), a toner image formed on a photosensitive drum ( ) is transferred to a recording sheet by applying a voltage (transfer voltage) to a transfer roller ( ). The value of the voltage to be applied is determined by performing a feed back sequence based on information obtained after a predetermined number of recording sheets have been recorded. The point when a current detected in connection with the applied voltage has reached a predetermined value (&agr;) is considered the saturation of the applied voltage. Once this point is reached, there will be no feed back sequences to be performed. After the application voltage saturation, therefore, it is possible to continue the printing operation without any interruption since no feed back sequence is performed. This shortens a job duration.
