发明名称 Image forming apparatus featuring accurate positioning of an intermediate transfer roller relative to a main body of the apparatus
摘要 An image forming apparatus includes an image bearing member which bears a toner image; an intermediate transfer member on which the toner image on the image bearing member is primary transferred; an intermediate transfer unit which supports the intermediate transfer member to allow rotation of the intermediate transfer member; a secondary transfer member which secondly transfers the toner image on the intermediate transfer member to a recording medium; a main body frame including at least the secondary transfer member; an opening unit which supports the intermediate transfer unit and which allows the intermediate transfer member to swing relative to the main body frame by pivoting on a rotation axis on the main body frame, thereby exposing the intermediate transfer unit when the intermediate transfer unit swings away from the main body frame; and a fitting portion which fits with the intermediate transfer unit, the fitting portion being disposed on the main body frame at a nearer portion to the intermediate transfer member than the rotation axis.
