    Abstract: A fixing device includes a heating belt, a heat source, a pressuring body, a pressing member and a sheet member. The heating belt is endless and heats a medium while being circulated. The heat source supplies heat to the heating belt. The pressuring body forms a nip with the heating belt, rotates so as to circulate the heating belt and presses the medium with the heating belt. The pressing member is disposed inside the heating belt and presses the heating belt against the pressuring body at the nip. The sheet member is held between the heating belt and the pressing member, attached to the pressing member at a center side portion and both end side portions in a longitudinal direction of the sheet member and has a heat shrinkable property. The both end side portions are shiftable in the longitudinal direction greater than the center side portion.

    Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source and a reflecting member. The fixing belt is arranged rotatably around a rotation axis. The reflecting member reflects the radiant heat radiated from the heat source. The fixing belt has a passing region and a non-passing region. Through the passing region, a recording medium passes. The non-passing region is arranged outside the passing region in a direction of the rotation axis. The reflecting member has a first reflecting part and a second reflecting part. The first reflecting part is arranged at an inner circumferential side of the passing region. The second reflecting part is arranged at an inner circumferential side of the non-passing region. Roughness of a face at the heat source side of the second reflecting part is larger than roughness of a face at the heat source side of the first reflecting part.

    Abstract: A fixing device includes a fixing belt, a heater, a pressure roller, a heater support member, and a restriction portion. The heater is in contact with an inner peripheral surface of the fixing belt. An end portion of the heater in a width direction of the fixing belt is exposed to outside the fixing belt. The pressure roller is provided to face a contact surface of the heater across the fixing belt, the contact surface being in contact with the fixing belt, the pressure roller being pressed against the fixing belt. The heater support member supports the heater by being in contact with a surface of the heater opposite from the contact surface. The restriction portion restricts the contact surface from moving toward the pressure roller at outside the fixing belt in the width direction.

    Abstract: A fixing device includes a fixing belt, a pressuring member, a pressing member, a shape restricting member and an elastic body. The fixing belt is configured to be rotatable. The pressuring member is configured to be rotatable and to come into pressure contact with the fixing belt so as to form a fixing nip. The pressing member is configured to press the fixing belt to a side of the pressuring member. The shape restricting member is configured to restrict a shape of the fixing belt and having an arc-shaped insertion part to be inserted into an end part of the fixing belt. The elastic body is attached to an end part in a circumferential direction of the insertion part.

    Abstract: A fixing device includes a fixing belt, a pressuring member, a pressing member and a sheet member. The fixing belt is arranged rotatably and configured to extend along an axis direction. The pressuring member is arranged rotatably and configured to come into pressure contact with the fixing belt so as to form a fixing nip. The pressing member is configured to press the fixing belt to a side of the pressuring member and configured such that the fixing belt is interposed between the pressing member and the pressuring member. The sheet member is formed in a tubular shape and provided around the pressing member and configured to rotate with rotation of the fixing belt.

    Abstract: An image forming apparatus includes a controller that controls rotational driving of a magnetic roller and rotational driving of a developing roller. The controller is capable of performing a toner collecting mode when no image formation is performed. In the toner collecting mode, the magnetic roller and the developing roller are intermittently rotated in a direction reverse to a direction in which the magnetic roller and the developing roller are rotated during image formation, then the magnetic roller is made to rotate in a forward direction, and then, the magnetic roller is rotated in a backward direction.
