Abstract:
1. An image forming apparatus, comprising: an image carrier to form a latent image thereon according to image information; an image forming device provided with a developing device that develops the latent image formed on the image carrier into a toner image by applying toner to the latent image formed on the image carrier; a transfer device provided at a location that faces the image carrier via a transfer body to form a transfer nip with the image carrier and supplied with a transfer bias to transfer the toner image formed on the image carrier to the transfer body at the transfer nip; and a controller device to: wherein the controller device controls, according to a determination result indicating that the first toner image has a portion that is not superimposed by the second toner image: the transfer bias that causes the second toner image to be transferred such that a transfer electric field generated at a portion of the transfer body to which the second toner image is transferred is less than a transfer electric field expected to be generated at the transfer body when no first toner image is formed on the transfer body; and a developing voltage that controls the amount of toner to be adhered from the developing device to the image carrier to form the second toner image such that toner adhesion at the portion of the transfer body to which the second toner image is transferred is greater than toner adhesion expected to be generated at the transfer body when no first toner image is formed on the transfer body.
