IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

Provided is an image forming apparatus including: a latent image carrier; a charging unit; a latent image forming unit; a developing unit that has a toner carrier; a transferring unit that transfers the toner image on the transfer medium; and a cleaning unit that removes a toner that remains to be adhered to the latent image carrier, wherein the toner carrier carries a toner layer including a contact toner that is directly in contact with the surface of the toner carrier and a non-contact toner that is not directly in contact with the surface of the toner carrier on the surface thereof, and wherein a voltage of the transferring bias is a DC voltage that does not generate discharge between the image portion of the latent image carrier and the transfer medium but generate discharge between the non-image portion of the latent image carrier and the transfer medium.
