Transfer device and image forming apparatus for suppressing image defects occurring in an image transfer

摘要

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.

主权项

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 intermediate transfer belt; an opposed member that abuts against an inner peripheral surface of the intermediate transfer belt, the opposed member being opposed to the second transfer member at the second transfer position; and an abutment member that is located upstream of the second transfer position with respect to a movement direction of the intermediate transfer belt, the abutment member being rotatably arranged so as to contact the inner peripheral surface of the intermediate transfer belt at a contact point, the contact point of the abutment member with the inner peripheral surface of the intermediate transfer belt being located on the second transfer member side of a region defined by an imaginary line extended in a direction orthogonal to an imaginary normal, the imaginary normal being drawn to connect a center of the opposed member and a center of the second transfer member at the second transfer position, the imaginary line extending through a point between the second transfer member and the opposed member.
