A jacket includes: a first layer that is on a cylinder body side when the jacket is attached to a rotating cylinder body; and a second layer that is a layer located on a side opposite to the cylinder body with respect to the first layer, has a hardness lower than that of the first layer, and does not exist at a position where at least one of end edges of the cylinder body in a rotation axis direction is located inward of the first layer in the rotation axis direction.

Jacket, transfer device, and image forming device

A transfer member includes: an inner layer; an outer layer provided on an outer periphery of the inner layer; and a surface layer provided on an outer periphery of the outer layer, both end portions of the surface layer in circumferential directions extending in the circumferential directions from both end portions of the outer layer in the circumferential directions.

An image forming apparatus includes: an image holder configured to hold an image formed using an electrographic process; a transfer body that faces the image holder and is configured to contact the image holder while rotating to form a secondary transfer region; an application unit configured to apply a voltage for charging the secondary transfer region; and a charge unit that faces a region other than the secondary transfer region of the transfer body and is configured to charge a surface of the transfer body with a polarity opposite to an applied voltage of the application unit.

A rotation device includes: a rotary body having a recess in an outer peripheral surface thereof; and a brush configured to come into contact with the outer peripheral surface of the rotary body to remove a foreign matter adhering to the outer peripheral surface, in which the brush is separated from the outer peripheral surface of the rotary body in a state where rotation of the rotary body is stopped.

Rotation device and image forming apparatus

A transfer device includes a transfer unit that transfers an image on an image carrier carrying the image onto a first surface of a recording material by applying a voltage containing an alternating-current component to the recording material; and a humidifying unit that humidifies the recording material transported toward the transfer unit from a second surface of the recording material that is opposite to the first surface.

Transfer unit comprising alternating current bias and humidifying unit

A transfer device includes a holding body, a transfer body, and a setting portion. The holding body holds multiple layers including a base layer formed of a toner having a mass larger than a threshold. The toner is electrically charged by a charging device. The transfer body transfers the layers on the holding body to a recording medium. The setting portion sets the charging device so that the charging device electrically charges a toner immediately after being transferred to the holding body with a larger amount of electric charges when the base layer is located uppermost on the holding body, than when the base layer is located other than uppermost on the holding body.

An image forming apparatus includes a first image forming portion that uses toner containing flat pigment; a second image forming portion that uses toner not containing the flat pigment; and a toner image carrier that carries a first toner image that is formed in the first image forming portion and a second toner image that is formed in the second image forming portion. The image forming apparatus has a mode in which a relationship Am&#x3c;Ac is satisfied, where Am denotes a number of toner layers of the first toner image that is carried by the toner image carrier, and Ac denotes the number of toner layers of the second toner image that is carried by the toner image carrier.

Image forming apparatus using flat toner to obtain a gloss

An image forming apparatus includes: an image forming unit that includes a developing device which performs development with a toner having a metal color which contains a flat metal pigment and a developing device which performs development with a toner having another color other than the metal color which does not contains a flat metal pigment, and forms a toner image on a recording medium; a fixing unit that fixes the toner image formed on the recording medium; and a controller that controls the image forming unit and the fixing unit such that a toner image is formed of the toner having the metal color and fixed on one surface of a film, and controls transport of the film as defined herein.

Image forming apparatus

An image forming apparatus includes: a first image forming section that uses a toner containing flat pigment particles; a second image forming section that uses a toner not containing the flat pigment particles; and a fixing section that fixes an image formed on a recording medium to the recording medium using heat. The quantity of heat that the fixing section applies to the image is increased in the case where the image formed on the recording medium using the toner containing the flat pigment particles is to be fixed compared to a case where the image formed on the recording medium using the toner not containing the flat pigment particles is to be fixed.

Image forming apparatus fixing of toner containing flat particles

An image forming apparatus includes an image forming unit, a heating unit, and a fixing unit. The image forming unit uses a toner including a flat pigment. The heating unit heats a recording medium. The fixing unit allows the recording medium to pass therethrough so as to cause an image formed on the recording medium to be fixed onto the recording medium by heat. In the image forming apparatus, the heating unit heats the recording medium on which the image has not been formed, the image forming unit forms the image on the recording medium having been heated, and the fixing unit fixes the image having been formed onto the recording medium.

Image forming apparatus utilizing flat pigment

An image forming apparatus includes a first forming unit that forms a first image by using a toner that contains a pigment other than a flat pigment; a second forming unit that forms a second image by using a toner that contains a flat pigment; a transfer body that transports the first image and the second image transferred thereon and transfers the first image and the second image onto a recording medium; a first transfer member that nips the transfer body in cooperation with the first forming unit with a first load and transfers the first image from the first forming unit onto the transfer body; and a second transfer member that nips the transfer body in cooperation with the second forming unit with a second load, which is larger than the first load, and transfers the second image from the second forming unit onto the transfer body.
