摘要： A roller member includes a cored bar, an elastic layer, a first high resistance member, and a second high resistance member. The elastic layer is disposed on an outer circumferential face of the cored bar. The cored bar has a projecting portion projecting beyond a range in which the elastic layer is disposed, toward an axial end of the cored bar. The first high resistance member is made of a high-resistance material having a higher electrical resistance than an electrical resistance of the cored bar. The first high resistance member is fitted to the projecting portion. The second high resistance member is made of a high-resistance material having a higher electrical resistance than an electrical resistance of the cored bar. The second high resistance member fills a space between the first high resistance member and the elastic layer.

摘要： A transfer device includes an image bearer and a transfer rotator. The transfer device further includes an adjuster including a rotatable cam and an opposed member opposed to the cam. The cam alternately contacts and separates the transfer rotator against and from the image bearer, having a continuous sloped surface with a plurality of positions, each position to contact the opposed member to obtain a different amount of separation between the image bearer and the transfer rotator. The transfer device further includes a controller to control the adjuster to adjust the amount of separation between the transfer rotator and the image bearer according to thickness or type of the recording medium when the recording medium starts to enter the transfer nip.

摘要： The image forming apparatus includes an image bearing member bearing a toner image; a driving roller and a tension roller movable in such a direction that the interval between the rollers changes; a transfer belt stretched by the rollers to feed a receiving material so that the toner image on the image bearing member is transferred onto the receiving material or to directly receive the toner image from the image bearing member; a detector opposed to the tension roller with the belt therebetween to optically detect a mark on the belt, wherein the detector is movably supported while biased toward the tension roller, and the moving direction of the tension roller is substantially the same as an optical axis of light emitted by the detector; and a regulator to regulate movement of the tension roller and the detector in a direction perpendicular to the moving direction of the tension roller.

摘要： In an image forming apparatus, a moving member is provided with a first engagement member. A lever is provided with a second engagement member to engage and disengage the first engagement member provided in the moving member. The lever moves between a predetermined first position and a second position different from the first position to move the moving member in such a manner that when the lever is at the first position, a transfer member reaches a contact position at which the transfer member is pressed against an image carrier via a belt, and when the lever is at the second position, the transfer member reaches a separation position at which the transfer member separates from the image carrier.

摘要： An image forming apparatus includes a developing device, an image bearer, a transfer rotator, a blade contacting a surface of the transfer rotator, and a controller to control the developing device, the image bearer, and the transfer rotator. A first toner pattern image is formed on the image bearer, transferred onto the transfer rotator, and passed past the blade at least twice together with rotation of the transfer rotator in at start-up of the image forming apparatus. A second toner pattern image is formed on the image bearer after the start-up and during passage of a non-image area in which toner images are not formed. A range of the first toner pattern image is wider than a range of the second toner pattern image in a width direction perpendicular to a direction of travel of the image bearer.
