Abstract
An image forming apparatus including an endless intermediate transfer member stretched over a plurality of rollers; a first biasing member; a secondary transfer roller to be pressed against a surface of the intermediate transfer member by the first biasing member; an opposed roller disposed opposite the secondary transfer roller to thus form a secondary transfer nip at which the toner image carried on the intermediate transfer member is transferred onto a recording medium; and a second biasing member to bias the opposed roller. The secondary transfer roller and the opposed roller are movable along a line connecting respective axes of the rollers and a pressure Fapplied by the first biasing member to the secondary transfer roller at the secondary transfer nip is greater than a pressure Fapplied to the opposed roller by the second biasing member at the secondary transfer nip.
