Abstract:
An image forming unit of an image forming apparatus includes a developing device and a toner replenishing unit that replenishes the developing device with toner. The toner replenishing unit includes an upper toner container, a lower toner container, a toner conveyance unit, and a replenishment control unit. The upper toner container and the lower toner container are disposed adjacently to each other in a vertical direction in an apparatus body. When the upper toner container becomes empty, the replenishment control unit controls the toner replenishing unit so as to replenish the developing device with the toner from the lower toner container.

Claim (Index 1):
An image forming apparatus comprising:\n an apparatus body; at least one image forming unit configured to form a toner image; and a transfer unit configured to transfer the toner image onto a sheet, wherein the image forming unit includes: a photoreceptor drum rotated about a predetermined axis and having a peripheral surface that allows formation of an electrostatic latent image and supports the toner image corresponding to the electrostatic latent image; a developing device configured to supply the photoreceptor drum with toner to visualize the electrostatic latent image in the toner image, the developing device including a toner replenishing port for internally receiving the toner; and a toner replenishing unit disposed above the developing device and configured to replenish the developing device with the toner through the toner replenishing port, the toner replenishing unit includes: a first toner container extending along an axial direction of the photoreceptor drum and configured to store and discharge the toner; a second toner container extending along the axial direction and configured to store and discharge the toner; a first container mounting unit disposed with a space above the developing device in the apparatus body, the first container mounting unit allowing the first toner container to be mounted along the axial direction and receiving the first toner container; a second container mounting unit disposed above the developing device and below the first container mounting unit in the apparatus body, the second container mounting unit allowing the second toner container to be mounted along the axial direction and receiving the second toner container; and a toner conveyance unit configured to convey the toner discharged from the first toner container mounted in the first container mounting unit and the second toner container mounted in the second container mounting unit to the developing device.
