Abstract:
1. An image forming apparatus comprising: a latent image carrier that carries a latent image; a developing unit that develops the latent image on the latent image carrier with toner to obtain a toner image; a nip forming member that comes into contact with the latent image carrier to form a transfer nip; and a transfer current output unit that outputs a transfer current having a same current value as a predetermined target value to the nip forming member to transfer the toner image on the latent image carrier to the nip forming member or a recording member held on a surface of the nip forming member, and determines the target value based on an algorithm representing a relationship between an image area ratio of the toner image on the latent image carrier and the target value and the image area ratio, wherein a first transfer step in which the toner image on the latent image carrier is transferred to the nip forming member or the recording member to which no toner image is transferred and a second transfer step in which the toner image on the latent image carrier is transferred to be superimposed on the toner image of the nip forming member or the recording member to which the toner image has already been transferred are performed to form a superimposed toner image, and the transfer current output unit is configured to perform processing as the algorithm for the second transfer step in which the target value having a smaller value is related to a same image area ratio compared to the algorithm for the first transfer step.
