Abstract

A transfer device includes an image carrier that carries a toner image; a nip forming member that forms a transfer nip between the nip forming member and the image carrier by contacting with a front surface of the image carrier; and a transfer bias applying unit that applies a transfer bias, thereby transferring the toner image carried on the image carrier to a recording material at a position of the transfer nip. The transfer bias applying unit applies the transfer bias in which an AC component and a DC component are superimposed and in which a peak-to-peak voltage of the AC component is larger than 6 times an absolute value of a voltage of the DC component.
