Abstract: A fixing device includes a fixing roller, a pressure roller, and a regulation member. The fixing roller includes a roller member and a fixing belt. The roller member includes a shaft which extends in one direction and an elastic layer integrally formed on the shaft. Each regulation member has an annular regulation surface which opposes a side edge of the fixing belt, and is configured to regulate movement of the fixing belt in a rotation axis direction. The regulation surface is inclined relative to a line perpendicular to the rotation axis as viewed on a cross-section parallel to the rotation axis. The regulation surface is inclined from the rotation axis side such that the closer the regulation surface is to an outside, in a radial direction, of the fixing roller, the closer the regulation surface is to a center, in a length direction, of the shaft.

Abstract: The fixing device includes a fixing belt, a pressing member, a pushing member and a cap. The fixing belt is endless and rotatable. The pressing member is configured to form a pressing area with the fixing belt. The pushing member is configured to come into contact with an inner circumferential face of the fixing belt via a lubricant and to push the fixing belt to the pressing member at the pressing area. The cap is configured to be attached to an end portion of the fixing belt through an elastic member. The cap has a contact part with which an end face of the fixing belt comes into contact. The contact part has a groove configured to store the lubricant leaked from the fixing belt. The groove is formed such that a width is varied along a radial direction of the cap.

Abstract: A fixing device includes a heating body, a pressuring body, a heat source and a detecting mechanism. The detecting mechanism is not in contact with the heating body and including an infrared detecting element which detects infrared rays radiated from an outer circumferential face of the heating body. A longitudinal direction of the heating body is a second direction which crosses a first direction as a conveying direction of a recording medium. A detected area is arranged on the outer circumferential face of the heating body so that the infrared rays radiated from the detected area is detected by the infrared detecting element. The detecting mechanism is arranged in a posture inclined to another posture facing the outer circumferential face of the heating body so that a width in the second direction of the detected area is wider than a width in the first direction of the detected area.

Abstract: A fixing device includes a first rotating member, a second rotating member and a blowing unit. The first rotating member is heated by a heat source. The second rotating member is pressed against the first rotating member to form a fixing nip with the first rotating member along a conveying path of a recording medium. The blowing unit blows a cooling airflow toward the first rotating member. An airflow route from the blowing unit to the first rotating member is arranged so as to cross the conveying path.

Abstract: A fixing device includes a fixing belt, a heating source and a fixing roller. The fixing belt has a sheet passing part and a non-sheet passing part. The fixing roller includes an elastic layer including first and second elastic parts. The first elastic part is provided on an inner diameter side of the sheet passing part. The second elastic part is provided on an inner diameter side of the non-sheet passing part. A gap is formed between a part of the elastic layer and the fixing belt in a state where the fixing belt is not heated. The part of the elastic layer is in close contact with the fixing belt in a state where the fixing belt is heated. The first elastic part includes a small-diameter part having a smaller external diameter than a part with a maximum external diameter of the second elastic part.

Abstract: An image forming apparatus has an operation panel and is operable from an operation panel and a mobile terminal. The image forming apparatus includes a holding unit, a vibration detecting unit, a communication unit, and a terminal recognition unit. The holding unit holds the mobile terminal. The vibration detecting unit detects a vibration of the mobile terminal held by the holding unit. The communication unit receives operation information wirelessly from the mobile terminal. The terminal recognition unit recognizes the mobile terminal from which an operation is to be accepted, on the condition that the timing of reception of the operation information by the communication unit coincides with the timing of detection of the vibration by the vibration detecting unit. The image forming apparatus disables acceptance of an operation from the operation panel in the case of accepting an operation from the mobile terminal.

Abstract: A fixing device includes a fixing member, a pressing member, a charger and an air discharging device. The fixing member is rotatably provided and heated by a heat source. The pressing member is rotatably provided and brought into pressure contact with the fixing member to form a fixing nip through which a sheet having a toner image is passed. The charger is disposed to oppose to the fixing member and applies an electric charge of the same polarity as a toner constituting the toner image to a surface of the fixing member. The air discharging device discharges an air flow passed between the fixing member and the charger via a filter.
