Abstract
A transfer device includes a transfer roller that has a characteristic in which an electrical resistance is changed in accordance with a rotation speed, contacts a transferred body that moves in synchronization with movement of an image holding body holding a toner image, and transfers the toner image held by the image holding body on the transferred body by applying a transfer voltage to the transferred body; and a regulator that regulates the rotation speed of the transfer roller independently from the movement of the image holding body and the transferred body.
Claims6
A transfer device, comprising:
- a transfer roller that has a characteristic in which an electrical resistance is decreased with an increase in a rotation speed of the transfer roller, contacts a transferred body that moves in synchronization with movement of an image holding body holding a toner image, and transfers the toner image held by the image holding body onto the transferred body by applying a transfer voltage to the transferred body;
- and
- a regulator that regulates the rotation speed of the transfer roller independently from the movement of the image holding body and the transferred body.
