There is described an image forming apparatus which forms a toner image on a transfer material by transferring a toner image from a photoreceptor element to an intermediate transfer member and then transferring the toner image from the intermediate transfer member to the transfer sheet. The apparatus includes: a developing section to develop the electrostatic latent image with toner so as to form the toner image; a first transferring section to transfer the toner image formed on the photoreceptor element onto the intermediate transfer element; a second transferring section to further transfer the toner image onto a transfer material; a lubricant supplying section to supply a lubricant, which includes at least a fatty acid calcium salt, onto the photoreceptor element in such a manner that the lubricant is added to the toner; and a polishing section to polish a surface of the intermediate transfer element.
