Abstract
A belt device includes an endless belt including at least a base layer and a coat layer, the coat layer formed on the base layer and configuring an upper most surface of the belt; a driving member that rotates the belt and that is provided at one end of the belt to bias an inner circumferential surface of the belt; and a driven member that rotates the belt and that is provided at other end of the belt to bias the inner circumferential surface of the belt. Wherein the base layer has a mirror specularity of 20-60.

A belt device, comprising:
- an endless belt including at least a base layer and a coat layer, the coat layer formed on the base layer and configuring an upper most surface of the belt;
- a driving member that is provided inside the belt to bias an inner circumferential surface of the belt, and that is configured to rotate the belt;
- and
- a driven member that is provided inside the belt to bias the inner circumferential surface of the belt, and that is driven by the belt as the belt is rotated by the driving member, wherein
- the base layer has a mirror specularity of 20-60, and
- a layer thickness of the coat layer is 100 nm-500 nm.

A transferring unit, comprising:
- a belt device comprising:
- an endless belt including at least a base layer and a coat layer, the coat layer formed on the base layer and configuring an upper most surface of the belt;
- a driving member that is provided inside the belt to bias an inner circumferential surface of the belt, and that is configured to rotate the belt;
- and
- a driven member that is provided inside the belt to bias the inner circumferential surface of the belt, and that is driven by the belt as the belt is rotated by the driving member, wherein
- the base layer has a mirror specularity of 20-60,
- a layer thickness of the coat layer is 100 nm-500 nm, and
- a transferring roller is provided at an inner circumferential surface of the belt, on which a bias voltage is applied, and transfers a toner image to the belt or a recording medium provided on the belt.
