Abstract

An image forming apparatus includes a transfer bias output device and an information receiving device (51; 52; 50). The transfer bias output device (39) outputs a transfer bias including a superimposed bias composed of an AC bias superimposed on a DC bias to form a transfer electric field in a transfer nip between an image bearing member (31) bearing a toner image and a nip forming member (36), to transfer the toner image onto a recording medium in the transfer nip. A controller operatively connected to the information receiving device (51; 52; 50) and the transfer bias output device causes the transfer bias output device to change a target output of a peak-to-peak voltage of the AC bias based on information received by the information receiving device (51; 52; 50) that affects transfer of the toner image and to reduce a target output of the DC bias as the target output value of the peak-to-peak voltage of the AC bias increases.
