Abstract
An intermediate transfer belt includes a base layer that has ionic conductivity and is a thickest layer out of multiple layers making up the intermediate transfer belt with respect to the thickness direction of the intermediate transfer belt, and an inner layer having electronic conductivity and a lower electrical resistance than the base layer.
Claims20
An image forming apparatus, comprising:
- an image bearing member configured to bear a toner image;
- a movable endless intermediate transfer belt that has electrical conductivity and is configured of a plurality of layers;
- a secondary transfer member configured to come into contact with an outer peripheral surface of the intermediate transfer belt, and configured to transfer a toner image from the intermediate transfer belt onto a transfer medium;
- and
- a power source configured to apply voltage to the secondary transfer member,
- wherein the toner image borne by the image bearing member is transferred by primary transfer to the intermediate transfer belt, and the toner image borne by the intermediate transfer belt is transferred by secondary transfer to the transfer medium by applying voltage from the power source to the secondary transfer member,
- and wherein the plurality of layers of the intermediate transfer belt includes
- a first layer that has ionic conductivity and is a thickest layer out of the plurality of layers making up the intermediate transfer belt with respect to the thickness direction of the intermediate transfer belt, and
- a second layer having electronic conductivity and a lower electrical resistance than the first layer.
