摘要： A toner cartridge includes a toner supply pipe and a first shutter. The toner supply pipe has a toner supply opening. When the toner cartridge is mounted onto a main unit, the toner supply pipe moves through an insertion opening from an outside position at which the toner supply opening is located outside a developing frame to an inside position at which the toner supply opening is located inside the developing frame. The first shutter is provided at the toner supply pipe. The first shutter moves relative to the toner supply pipe between an open position at which the toner supply opening is opened and a closed position at which the toner supply opening is closed. The first shutter moves relative to the toner supply pipe from the closed position to the open position in a state where the toner supply pipe is located at the inside position.

摘要： A shutter moves between a closed position at which the shutter covers a nip of a fuser and an open position at which the nip is exposed. A link contacts a cartridge. The link is coupled to the shutter and moves the shutter between the open position and the closed position. The link is movable between a first position at which the cartridge is not attached to an apparatus main body and a second position at which the cartridge is attached to the apparatus main body. When the cartridge being attached to the apparatus main body contacts the link, the shutter moves from the closed position toward the open position. Before the shutter reaches the open position, the link and the cartridge separate from each other. The link having separated from the cartridge moves further in a direction in which the shutter becomes the open position.

摘要： A chute is located between a transfer roller and a fuser in a direction crossing both a first direction along a drum axis direction and a second direction crossing the first direction. The chute causes a sheet having passed through a transfer nip to be directed toward a fixing nip. The chute is movable in the second direction between a first position and a second position shifted from the first position toward one side in the second direction. The chute located at the second position is farther away from an imaginary plane passing through the nips than the chute located at the first position. A reciprocating mechanism is located on an other side of the chute in the second direction. The reciprocating mechanism reciprocates by drive force from the drive source and presses the chute to move between the first position and the second position.

摘要： An image-forming apparatus includes a housing, a cartridge, and a fixing device. The fixing device includes a heating member, a fixing frame, and a shutter movable between an open position for opening an opening of the fixing frame and a closed position for closing the opening. The housing includes: a guide frame for guiding a guide protrusion of the cartridge for attachment of the cartridge to the housing; and a connection link connected to the shutter and positioned opposite the cartridge with respect to the guide frame. The connection link moves the shutter to the open position in conjunction with the attachment of the cartridge to the housing, and moves the shutter to the closed position in conjunction with detachment of the cartridge from the housing. The connection link abuts on the guide protrusion through a through-hole of the guide frame during the attachment of the cartridge to the housing.

摘要： A controller is configured to control a print engine and a conveyor to form an image on both sides of a sheet. The controller is configured to: in a case where images to be formed on both sides of each of an Nth (N is a positive integer) sheet, an (N+1)th sheet, and an (N+2)th sheet are all monochrome image or all color image, convey the (N+2)th sheet to the print engine and form an image before forming an image on both sides of the (N+1)th sheet; and in a case where the images to be formed on both sides of each of the Nth sheet, the (N+1)th sheet, and the (N+2)th sheet are a mixture of the monochrome image and the color image, convey the (N+2)th sheet to the print engine and form an image after forming an image on both sides of the (N+1)th sheet.
