  • Patent number: 10095177
    Abstract: A cleaning unit includes a cleaning member, an accommodating portion, and a transport member. The cleaning member removes a developer from a surface of an image carrier. The accommodating portion accommodates the removed developer. The transport member transports the developer removed by the cleaning member to the accommodating portion. The transport member includes a shaft member and first and second transport bodies. The shaft member extends in a direction intersecting a transport direction of the developer. The first transport body is rotatably supported by the shaft member. The second transport body is rotatably supported by the first transport body at a position spaced from the shaft member. The second transport body extends toward the cleaning member. When the shaft member rotates, a trajectory of an end portion, at a cleaning member side, of the second transport body is an ellipse elongated along the transport direction on the cleaning member.

  • Patent number: 9459550
    Abstract: An applying device includes an applying member and a contact member. The applying member applies voltage to an image bearing member and has an elastic layer and an endless surface layer. The elastic layer is disposed facing the image bearing member, is rotatable about a rotation axis, and is composed of a foam material. The surface layer surrounds an outer periphery of the elastic layer, is supported by the elastic layer in a non-bonded state, and is rotatable together therewith. The contact member comes into contact with the surface layer at an upstream side, in a rotational direction of the applying member, relative to an imaginary line segment connecting a rotation axis of the image bearing member and the rotation axis of the applying member, so as to apply tension to the surface layer at a contact position between the image bearing member and the applying member.
