Abstract: In a toner conveying device, a conveyance path of toner is formed in the casing. A conveyance screw is supported by two support portions of the casing so as to be rotated in the conveyance path and convey the toner along the conveyance path. A low friction portion is provided on an inner side surface of the casing facing the conveyance screw, in a middle of the two support portions. The low friction portion has a lower friction coefficient with the conveyance screw than the other portions of the inner side surface. In a region along a longitudinal direction of the conveyance screw including the low friction portion, a space between the low friction portion and the conveyance screw is narrower than a space between the conveyance screw and portions of the inner side surface other than the portion on which the low friction portion is provided.

Abstract: A sorting device includes a base portion and a tray portion. The tray portion is supported on the base portion to be reciprocatable between a first shift position, where the tray portion is located at one side in the sheet width direction, and a second shift position, where the tray portion is located at the other side in the sheet width direction. The tray portion has a cutout portion. The cutout portion is formed by cutting away, with a predetermined width, an end part of the tray portion in the sheet width direction inward across the tray portion. With the tray portion at the second shift position, the cutout portion is located below one side end edge of the sheet in the sheet width direction, of sheets stacked on the tray portion.

Abstract: A toner conveying device includes a case that can store therein toner to be conveyed, a conveyance member rotatably supported at both ends thereof by the case and configured to rotate to convey the toner inside the case in a conveying direction set in advance, and a pushing member pushed against the conveyance member and configured to slide on an outer peripheral portion of the conveyance member as the conveyance member rotates. The pushing member includes a first sheet member having flexibility and abutting on the outer peripheral portion in a first direction intersecting with a rotational axis direction of the conveyance member to push the conveyance member and a second sheet member having flexibility and abutting on the outer peripheral portion in a second direction, which is different from the first direction, intersecting with the rotational axis direction to push the conveyance member.

Abstract: A fixing device includes a casing, a fixing member, a pressuring member, a pressure adjusting part and a correction biasing part.The fixing member heats a toner image on a medium while rotating inside the casing.The pressuring member forms a pressuring area with the fixing member while rotating inside the casing to pressure a toner on the medium passing through the pressuring area. The pressure adjusting part presses one of the fixing member and the pressuring member to the other to pressurize the pressuring area, and releases pressing of the one to depressurize the pressuring area.The correction biasing part, in a case where a supporting shaft part supporting the other by the casing penetrates the casing, biases both sides in an axial direction of the supporting shaft part extended to the outside of the casing in a similar direction to a pressurizing direction of the pressure adjusting part.

Abstract: An image forming apparatus includes a photosensitive drum, a cleaning blade, and a movement mechanism. The movement mechanism reciprocates the photosensitive drum in an axial direction of the photosensitive drum in a specific cycle. The movement mechanism includes a first cam gear and a second cam gear. The first cam gear rotates about an axis of the photosensitive drum together with the photosensitive drum. The second cam gear is restricted in position in the axial direction and rotates at a rotational speed different from that of the first cam gear. The first and second cam gears each have a plurality of coaxial cam portions. When top points and bottom points of the respective cam portions come in contact with one another by turns, the photosensitive drum moves in the axial direction.

Abstract: A driving device includes a motor, a pulley, a metal belt, a first unit, a second unit, a biasing member and a detector. The motor includes a drive shaft. The pulley includes an output shaft extending in parallel to the drive shaft. The pulley is rotatably supported on the first unit with the output shaft as a rotary shaft and the circumferential surface is arranged at a distance from the drive shaft in a radial direction of the rotation. The second unit supports the motor and is slidable relative to the first unit. The biasing member biases the second unit in a direction to move the drive shaft away from the output shaft in a state where the metal belt is mounted between the drive shaft and the pulley. The detector detects a change in an inter-axial distance between the drive shaft and the output shaft.

Abstract: An intermediate transfer unit is attached to a position in the main body portion from a front side of the main body portion along the depth direction in a detachable manner. A cover portion extends in the depth direction and along a region of the outer circumferential surface of a rotating image carrying member that is more on a downstream side in a rotation direction of the image carrying member than the top region of the rotating image carrying member that is in contact with the intermediate transfer belt. A shield portion is provided on a portion of an upper surface of the cover portion that is closer to a front surface of the main body portion than the intermediate transfer belt. The shield portion has a taper surface that is inclined diagonally downward from a top surface of the shield portion toward the intermediate transfer belt.
