    Abstract: An image forming apparatus includes a developing device, a drum unit, a side plate, a notch, a turning member and a biasing member. The developing device includes a developing roller. The drum unit includes a photosensitive drum and has a protrusion protruding in an axial direction of the photosensitive drum. Thea side plate faces an end surface of the drum unit in the axial direction. The notch is provided in the side plate. The turning member is capable of turning in a direction protruding into the notch and in a direction separating from the notch. The biasing member biases the turning member in a direction close to the notch.

  • Patent number: 11273381
    Abstract: First, an indication sign displayed on a display screen is moved so as to reach a first position at a predetermined timing. Next, when an operation input to an input section is performed at the predetermined timing, a parameter related to the indication sign is changed. Furthermore, when the parameter related to the indication sign does not satisfy a first condition after the parameter is changed, the indication sign is moved to a position different from the first position, and then is moved toward the first position again.

  • Patent number: 10365574
    Abstract: An image carrying member unit has an image carrying member, a charging member, a pair of first bearing members, a biasing member, and a supporting frame. The image carrying member is rotatable, and an electrostatic latent image is formed on it. The charging member is arranged in contact or close to the image carrying member, and electrostatically charges the image carrying member. The first bearing members support the charging member movably in directions to and away from the image carrying member. The biasing member biases the charging member toward the image carrying member. The supporting frame supports the image carrying member and the first bearing members. The first bearing members each have a fulcrum rotatably supported on the supporting frame, an arm extending radially from the fulcrum, and a bearing portion formed at a tip end of the arm and supporting axially either end of the charging member.

  • Patent number: 10241439
    Abstract: A lever member is displaceably provided to a toner container. A container locking mechanism locks the toner container at a mounting position in a container mounting portion when the lever member is operated from a first operation position to a second operation position in a state where the toner container is located at the mounting position. A locking member is displaceable between a lever locking position and a lever releasing position. A locking control portion controls a drive portion to displace the locking member to the lever locking position when a remaining amount of the toner detected by the remaining amount detection portion is equal to or greater than a predetermined amount, and controls the drive portion to displace the locking member to the lever releasing position when the remaining amount of the toner detected by the remaining amount detection portion is less than the predetermined amount.
