    摘要： A fixing device is equipped with a lower pressure roller, an upper pressure roller and a fixing belt which fix a toner image onto a sheet, by holding and conveying the sheet by a nip portion, and a control unit which controls rotation of the lower pressure roller. The control unit periodically changes a velocity of rotational drive of the lower pressure roller, at a frequency of which a period is shorter than a time needed for the sheet to pass through the nip portion, when the sheet passes through the nip portion.

    摘要： An image formation apparatus includes: a fixing belt wound on a plurality of support rollers including a first pressure applying roller; a second pressure applying roller applying a pressure to the first pressure applying roller and thus forming a nip portion N; a tension modifying mechanism adjusting a tension; a contact area adjustment mechanism adjusting a downstream contact area, which is a contact area of the fixing belt in contact with the first pressure applying roller that is located downstream of the nip portion N; a sheet information obtainer; and a controller controlling an operation of the tension modifying mechanism and an operation of the contact area adjustment mechanism. When sheet information indicates embossed paper, the controller adjusts the operation of the tension modifying mechanism and the operation of the contact area adjustment mechanism to reduce a tension exerted to the fixing belt and also reduce the downstream contact area.

    摘要： An image forming apparatus includes: a fixing unit receiving through an inlet a recording medium with a transferred toner image and heat fixing the toner image to the recording medium before discharging the recording medium from an outlet; a suction part for sucking the recording medium through a recording-medium suction opening, the recording medium conveyed on a recording medium conveyance path leading to the inlet; an exhaust passage for discharging to the outside a gas sucked by the suction part; and a filter disposed in the exhaust passage and serving to capture fine particles generated from the fixing unit and sucked in by the suction part.
