An image forming apparatus includes a toner image carrier, a transfer roller, a fixing device, a movable chute, a movement device, and a controller. The transfer roller forms a transfer nip with the toner image carrier. The fixing device includes a rotatable heating body and a rotatable pressure body configured to form a fixing nip with the rotatable heating body. The movable chute guides the sheet and is movable between a first position and a second position located further away, than the first position, from a straight line connecting a downstream edge of the transfer nip and an upstream edge of the fixing nip. The controller controls the movement device to move the movable chute only between the first position and the second position. The movable chute is movable to a third position located further away, than the second position, from the straight line.

A fixing apparatus includes first and second rotating members, a heater having a heating element and a substrate, and first and second contact members. A direction of a longer side on a surface of the substrate where the heating element is disposed is a longitudinal direction. A direction intersecting the longitudinal direction is a widthwise direction. The first contact member is disposed in a region outside a region where a maximum size recording material conveyed to a nip portion passes through the nip portion on one end side in the longitudinal direction on an outer circumferential surface of the first rotating member, and the second contact member is disposed in the region outside the region where the maximum size recording material conveyed to the nip portion passes through the nip portion on an other end side in the longitudinal direction on an outer circumferential surface of the second rotating member.

A fixing device detachably attachable to an image forming apparatus includes a housing frame having an open front side in an insertion direction in which the fixing device is inserted into the image forming apparatus. The housing frame includes a support plate, as a back side of the housing frame in the insertion direction, and a pair of side plates extending in the insertion direction. The support plate includes an extension extending beyond one of the pair of side plates. The extension includes an engaged portion to be engaged with an engaging portion of the image forming apparatus when the fixing device is mounted on the image forming apparatus.

A fuser driving device is provided and includes a front frame and a rear frame. The front frame and the rear frame are fixedly connected to each other. Two ends of a gear are respectively mounted to the front frame and the rear frame. A driving arm is mounted in the gear and is movable axially along the gear to enter into or withdraw from the fuser. When the driving arm enters into the fuser, the driving arm is driven to rotate through the gear, to drive a fusing roller to rotate. A withdrawing device includes a pulling member and an operating member. One end of the pulling member is connected to the driving arm and the other end is connected to the operating member. The pulling member is moved by operating the operating member to pull the driving arm to withdraw from the fuser into the gear.

An image-forming apparatus includes a housing, a sheet supply tray, an image forming unit, a drawer, a re-conveying path, and a re-conveying chute. The housing includes: a first side wall having a first opening; and a second side wall positioned apart from the first side wall in a first direction. The image forming unit includes a cartridge. The drawer is configured to support the cartridge, and is movable in the first direction relative to the housing through the first opening. The drawer supports a registration roller. The re-conveying path is positioned upward of the sheet supply tray. The re-conveying chute is configured to form a part of the re-conveying path, the part of the re-conveying path being positioned between the sheet supply tray and the drawer in an up-down direction.

A fixing device includes a heating member, a pressure member, a first side frame, a second side frame, a connection frame, an external connector, a first temperature sensor, a second temperature sensor, an intermediate circuit board, a first cable, a second cable, and a third cable. The fixing device is installable into a main housing of an image forming apparatus. The heating member and the pressure member are configured to nip a sheet therebetween. The connection frame connects the first side frame and the second side frame. The intermediate circuit board is configured to relay signals from the first temperature sensor and the second temperature sensor to the external connector. The first cable connects the first temperature sensor and the intermediate circuit board. The second cable connects the second temperature sensor and the intermediate circuit board. The third cable connects the intermediate circuit board and the external connector.

An image forming apparatus includes an apparatus body provided with an opening portion, an opening/closing member supported to be openable and closable with respect to the apparatus body between a closed position and an open position, a fixing unit, and a moving unit provided in the apparatus body and configured to move the fixing unit from a first position toward a second position. A movement of the fixing unit from the first position to the second position is restricted in a state in which the opening/closing member is positioned at the closed position and is allowed in a state in which the opening/closing member is positioned at the open position. The moving unit includes a support portion configured to support the fixing unit positioned at the second position, and a restricting portion configured to restrict dropping of the fixing unit supported by the support portion from the support portion.

An image forming apparatus includes an apparatus body provided with an opening portion, an opening/closing member, a fixing unit, and a moving unit provided in the apparatus body and configured to move the fixing unit from a first position toward a second position above the first position. Movement of the fixing unit from the first position to the second position is restricted in a state in which the opening/closing member is positioned at the closed position and is allowed in a state in which the opening/closing member is positioned at the open position. The moving unit includes a support portion configured to support the fixing unit positioned at the second position such that the fixing unit is attachable and detachable. The support portion extends in a longitudinal direction of the fixing unit and supports the fixing unit from below.

An image forming apparatus includes an image forming unit, a fixing unit, and a supporting device, wherein, when the fixing unit is at a first position, a moving member is positioned closer to a first rotation member than a virtual line connecting an end portion of a fixing nip portion where a recording medium enters and an end portion of the guide member on an upstream side in a recording medium conveyance direction when viewed in a rotation axis direction, and wherein, when the fixing unit is at a second position, the moving member is positioned such that at least one portion of the moving member is projecting toward a second rotation member relative to the virtual line.

An image forming apparatus includes: a body housing; an image forming unit configured to form a developer image on a sheet; a fixing device configured to be detached from an accommodate compartment of the body housing and configured to fix the developer image on the sheet; an outer cover moveable between a closed position where the accommodate compartment is covered and an opened position where the accommodate compartment is uncovered; and a sheet guide provided between the fixing device and the outer cover and configured to guide, to the image forming unit, the sheet discharged from the fixing device. The sheet guide is rotatably supported by the body housing about a first guide axis, and is moveable between a working position close to the fixing device and a retracted position rotated from the working position to outside of the body housing.
