TRANSFER DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME

摘要

A transfer device includes an image carrier, a transfer roller, and a moving unit. The moving unit moves the transfer roller between a nip formation state in which the transfer roller forms a transfer nipping portion in contact with the image carrier and a separated state in which the transfer roller is separated from the image carrier. In a contact operation of bringing the transfer roller into contact with the image carrier via the recording medium, the moving unit moves the transfer roller toward the image carrier at a moving velocity slower than that in a pressing operation of generating a predetermined nipping pressure by further moving the transfer roller toward the image carrier after the contact operation. The moving unit causes the recording medium to enter the transfer nipping portion in the contact operation.

主权项

1. A transfer device, comprising:
an image carrier to carry a toner image thereon; a transfer roller to form a transfer nipping portion in contact with the image carrier and transfer the toner image carried on the image carrier onto a recording medium entering the transfer nipping portion; and a moving unit to move the transfer roller between a nip formation state in which the transfer roller forms the transfer nipping portion in contact with the image carrier and a separated state in which the transfer roller is separated from the image carrier, wherein in a contact operation of bringing the transfer roller into contact with the image carrier via the recording medium, the moving unit moves the transfer roller toward the image carrier at a moving velocity slower than that in a pressing operation of generating a predetermined nipping pressure by further moving the transfer roller toward the image carrier after the contact operation, and the moving unit causes the recording medium to enter the transfer nipping portion in the contact operation.
