ABSTRACT:
In an image transfer device for an image forming equipment, a bias for image transfer is applied from a power source to an endless transfer belt via a bias roller. A current from the Transfer belt is released to ground via a ground electrode. Transfer control means variably controls a current I.sub.1 output from the power source that the difference between the current I.sub.1 and a current I.sub.2 flowing from the power source to the ground via the transfer belt, i,e., I.sub.out =I.sub.1 -1.sub.2 remains at a preselected target current. Setting means sets the target current on the basis of a set condition or conditions.
