摘要： In one embodiment, when a hot roller is driven to rotate, a driving gear rotates so that a swing gear and a swing cam rotate. Then, a sliding contact edge on the right side of a swing lever that abuts against the circumferential face of the swing cam repeatedly moves up and down, and the swing lever repeatedly rotates clockwise and counterclockwise with a shaft of a pressure release cam as the center. At this time, since only the clockwise rotation of the swing lever is transmitted via a one-way clutch to the shaft of the pressure release cam, the clockwise rotation is intermittently transmitted to the shaft of the pressure release cam. As a result of this, the pressure release cam intermittently rotates clockwise, and the pressure release cam pushes away a roller of a displacement frame, so that the pressure roller separates from the hot roller.

摘要： The present invention provides an image forming apparatus in which a recording paper to which a toner has been transferred is guided by a guide member and transported to a nip region between two rotatable members that are pressed against each other, and the toner on the recording paper is fixed at the nip region. In this image forming apparatus, a conductive or semiconductive region and an insulating region that are to be brought into contact with the recording paper are sequentially arranged in a recording paper transport direction on a guide face of the guide member, the conductive or semiconductive region is grounded, and the insulating region includes an end portion of the guide member oriented in the recording paper transport direction.

摘要： A fusing unit is comprised of a fusing roller and a pressing roller, having an elastic layer on their outer peripheral surface and a pressing structure for pressing the fusing roller against the pressing roller, and causes a sheet of paper with an unfixed toner image to pass through the nip portion where the fusing roller and pressing roller are put in press-contact with each other so as to fuse the toner image and fix it to the paper. This fusing unit further includes a pressure release lever for regulating the pressing action of the pressing structure when the rollers are put in press-contact with each other by the pressing structure.
