Abstract
An image forming machine comprising image bearing means, charging means, exposure means, reversal development means, transfer means, and cleaning means. The transfer means includes a rotationally driven transfer belt, and transfer voltage applicator means for applying a transfer voltage to the back side of the transfer belt. The transfer voltage applicator means applies the transfer voltage to the transfer belt over a predetermined effective transfer width. The face side of the transfer belt is brought into contact with the image bearing means via an image receiving member and directly over a predetermined effective contact width. The effective contact width is larger than an effective charging width and larger than the effective transfer width.
