Abstract
A controller controls a secondary transfer power source such that a current having a first value flows in a secondary transfer portion in a case where a transfer material with an image formed on a first surface thereof has been conveyed for less than a predetermined amount of time in a second conveyance path. Moreover, the controller controls the secondary transfer power source such that a current having a second value larger in absolute value than the first value flows in the secondary transfer portion in a case where the transfer material with an image formed on the first surface thereof is conveyed to the secondary transfer portion after waiting for the predetermined amount of time or more in the second conveyance path.
