ABSTRACT:
An image forming apparatus includes an image carrier, an exposure mechanism, a latent-image forming mechanism, at least one image forming mechanism including a development mechanism to develop the latent image, an intermediate transfer member disposed to contact the image carrier, a primary transfer mechanism to transfer a toner image on the image carrier and superimpose one toner image on another on the intermediate transfer member, a secondary transfer mechanism to transfer the toner image superimposed on the intermediate transfer member onto a transfer material, an asperity detector to detect an asperity profile of a surface of the transfer material to identify a concavity of the transfer material, and a toner adhesion control mechanism to increase an amount of the toner transferred to intermediate transfer member according to the concavities in the surface of the transfer material identified by an asperity detector, after a predetermined time elapses.
