Abstract: A cleaning device includes: a cleaning brush that has bristles that rotate and contact a surface, to which toner has adhered, of a cleaning member to be cleaned, the cleaning brush removing the toner adhered to the surface of the cleaning member; a first contact member that contacts the bristles without a position of the first contact member relative to a position of the cleaning brush being changed; and a second contact member that contacts the bristles at a location downstream from the first contact member in a direction of rotation of the cleaning brush and without a position of the second contact member relative to the position of the cleaning brush being changed, and that is disposed on an extension line extended from a line between an axial center of the cleaning brush and a base of the bristles that move away from the first contact member.

Abstract: A medium transport device includes a transport member and a guide member. The transport member supports and transports a medium. The guide member is shifted from the transport member in a width direction of the medium to guide the medium. The guide member includes contact portions that come into contact with the medium. The contact portions are spaced apart from one another in a transport direction of the medium.

Abstract: 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.

Abstract: An image forming apparatus includes: an image carrier configured to carry an image; a transfer unit configured to transfer the image to a medium; and a cleaner configured to remove deposits on a surface of the image carrier after passing through a position of the transfer unit, in which when a type of a medium to be used is a first medium, the cleaner improves an ability to remove the deposits from the image carrier as compared with a case where the medium to be used is a second medium having a lower transfer sensitivity than the first medium.
