Image forming apparatus

An image forming apparatus including an image forming unit configured to form a toner image on a recording material, and configured to perform a state transition to a power-off state and to a standby state where image forming by the image forming unit is possible, the image forming apparatus comprising:

• a fixing unit configured to fix the toner image on the recording material;
• a belt;
• a conveyance unit configured to form a conveyance nip portion with the belt and to nip and convey the recording material that has passed through the fixing unit;
• a heat sink configured to be in contact with an inner circumferential surface of the belt;
• first and second rollers configured to suspend the belt;
• a belt position detection unit configured to detect a position of the belt in a widthwise direction perpendicular to a thickness direction of the belt and a conveyance direction of the recording material nipped by the conveyance nip portion;
• a steering unit configured to swing the first roller relative to the second roller to widthwisely move the belt relative to the first roller, and to swing the first roller relative to a reference position where the first roller is approximately parallel to the second roller based on a detection result by the belt position detection unit;
• and
• a control unit configured to control the steering unit,
• wherein, when the image forming apparatus enters the power-off state and the first roller is inclined relative to the reference position, the control unit controls the steering unit to position the first roller at the reference position.
