Abstract

A transfer device includes an intermediate transfer belt that is stretched by multiple rollers, and transports a toner image on an outer peripheral surface, a second transfer member that performs second transfer that transfers the toner image to a recording medium at a second transfer position, an opposed member that abuts an inner peripheral surface of the intermediate transfer belt, and is opposed to the second transfer member at the second transfer position, and an abutment member that is rotatably arranged so as to contact the inner peripheral surface of the intermediate transfer belt at a contact point, the contact point being located on the second transfer member side of a region defined by an imaginary line extended orthogonally to an imaginary normal, the imaginary normal connecting a center of the opposed member and a center of the second transfer member at the second transfer position.

First claim

What is claimed is:

1. A transfer device comprising:
an intermediate transfer belt that is stretched by a plurality of rollers, the intermediate transfer belt configured to transport a toner image on an outer peripheral surface;
a second transfer member configured to perform second transfer, the second transfer transferring the toner image on the intermediate transfer belt to a recording medium at a second transfer position where the second transfer member is opposed to the inte…
