  • Patent number: 9823601
    Abstract: According to an embodiment, a developer-supplying container includes a container and a paddle. The container includes an opening for supplying the image forming apparatus with developer contained in the container. The paddle conveys the developer to the opening by rotating within the container. The paddle includes a first arm. The first arm has a shape that is wider on an upstream side in a direction of the rotation of the paddle and narrower toward a downstream side. In addition, the first arm is disposed such that a narrowest portion of the first arm is located at the same position as the opening in a direction of a shaft.

  • Patent number: 7333751
    Abstract: According to the present invention, when inserting and removing EPUs from an image forming unit, a support leg of a casing can swing, is inclined, and avoids easily a structural body on a path. Further, when putting the EPUs outside the main body of the image forming apparatus, the support leg is fixed to the casing. Therefore, the space for the support leg of the casing of the image forming unit to insert through can be reduced.

  • Patent number: 7127190
    Abstract: The present invention drives cleaning member moving devices for moving cleaning members of a plurality of chargers at the same time by a single cleaning motor to miniaturize an image forming apparatus and reduce the cost. Further, at the end time of cleaning, all the cleaning members are shifted to a predetermined area by the cleaning member moving devices, and the cleaning motor is stopped, thus the cleaning members remain in a charging area, and uneven charging is prevented.

  • Patent number: 7127197
    Abstract: An image forming apparatus includes a main body, an image carrier provided in the main body and configured to retain electrostatic latent images on its surface, and a developing unit including a holding unit holding plural developing devices, rotatably supported by the main body. Further, a driving source is configured to rotate the developing unit and move a desired developing device to a developing position opposed to the image carrier. A stopping member is configured to be moved to an unstopping position unengaged with the holding unit and to a stopping position to stop a one-way direction rotation of the developing unit at an exchanging position for exchanging the developing devices. A backstop member is configured to be moved to a removing position unengaged with the holding unit and to an engaged position engaged with the holding unit to prevent a rotation of the developing unit in a direction opposite the one-way direction rotation.
