  • Publication number: 20210294258
    Abstract: In an image forming apparatus capable of turning over a sheet to form images on both sides of the sheet, when duplex printing is executed successively on three or more sheets, a controller causes a first sheet conveyed from an image forming unit and a second sheet conveyed from the image forming unit to be guided into a first path by positioning a guide member in a first position, and then conveyed into a third path by a first roller, and causes a third and subsequent sheets conveyed from the image forming unit to be guided into a second path by positioning the guide member in a second position, and then conveyed into the third path by a second roller.

  • Publication number: 20200050129
    Abstract: 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.
