Abstract
A transfer device is provided and includes: a rotatable transfer roller; and a controller controls a balance of a pressure contact force exerted on the transfer roller in the axial direction, the controller including: a bearing member; a movable holding section that holds the bearing member; and a stationary holding section that holds the movable holding section. The movable holding section and the stationary holding section oppose each other by way of opposed surfaces, an adjustment unit is inserted into one of the opposed surfaces, and the movable holding section and the stationary holding section are arranged in such a manner that an extremity of the adjustment unit contacts the other of the opposed surfaces.
Claims6
A transfer device comprising:
- a rotatable transfer roller capable coming into pressure contact with a belt-shaped intermediate transfer member;
- and
- a controller that is provided at an end of the transfer roller in an axial direction thereof and that controls a balance of a pressure contact force exerted on the transfer roller in the axial direction,
- the controller including:
- a bearing member that rotatably supports the end of the transfer roller in the axial direction;
- a movable holding section that holds the bearing member by way of an elastic member forced in a direction of pressure contact and is able to move along the direction of pressure contact;
- and a stationary holding section that has a guide section for guiding the movable holding section in the direction of pressure contact and that holds the movable holding section so as to be relatively movable,
- the movable holding section and the stationary holding section opposing each other by way of opposed surfaces that are orthogonal to the direction of pressure contact,
- an adjustment unit being inserted into one of the opposed surfaces, and
- the movable holding section and the stationary holding section being arranged in such a manner that an extremity of the adjustment unit contacts the other of the opposed surfaces.
An image forming apparatus comprising:
- a transfer device comprising:
- a rotatable transfer roller capable coming into pressure contact with a belt-shaped intermediate transfer member;
- and
- a controller that is provided at an end of the transfer roller in an axial direction thereof and that controls a balance of a pressure contact force exerted on the transfer roller in the axial direction,
- the controller including:
- a bearing member that rotatably supports the end of the transfer roller in the axial direction;
- a movable holding section that holds the bearing member by way of an elastic member forced in a direction of pressure contact and is able to move along the direction of pressure contact;
- and a stationary holding section that has a guide section for guiding the movable holding section in the direction of pressure contact and that holds the movable holding section so as to be relatively movable,
- the movable holding section and the stationary holding section opposing each other by way of opposed surfaces that are orthogonal to the direction of pressure contact,
- an adjustment unit being inserted into one of the opposed surfaces, and
- the movable holding section and the stationary holding section being arranged in such a manner that an extremity of the adjustment unit contacts the other of the opposed surfaces;
- and
- an image forming unit that forms an image on a recording medium.
