In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.

An image forming apparatus includes a housing, a sheet conveyor, a sheet stacker, and circuitry. The sheet conveyor is configured to convey a sheet on which liquid is applied. The sheet stacker is configured to stack the sheet conveyed by the sheet conveyor. The circuitry is configured to control conveyance of the sheet. The circuitry is configured to cause the sheet conveyor to expose the sheet on which the liquid is applied, to an outside of the housing, and convey the sheet to the sheet stacker.

An image forming apparatus comprising includes an image carrying member including a movable surface to include a toner image; a transfer roller to form a transfer nip between the transfer roller and the movable surface of the image carrying member, to move position in a direction in correspondence to a thickness of a print medium to intersect a direction of introduction of the print medium into the transfer nip, and to receive a transfer bias voltage to transfer the toner image from the movable surface of the image carrying member to the print medium; and a movement guide structure to guide the print medium toward the transfer nip, and to move in synchronization with the movement of the position of the transfer roller to change a gap between an end of the movement guide structure facing the image carrying member and the image carrying member.

A cleaning device cleans a surface of a sheet conveyance member which conveys a sheet in an image forming apparatus that executes image forming processing using a recording material, the surface carrying a solid substance that originates from the recording material and that adheres to the surface. The cleaning device includes a cleaning member including a contact surface configured to come in contact with the surface of the sheet conveyance member. The contact surface is an irregular surface rougher than the surface of the sheet conveyance member. At cleaning of the surface, the cleaning member makes a relative movement to the surface of the sheet conveyance member. The irregular surface is an irregular surface configured to take away the solid substance adhering to the surface of the sheet conveyance member when the cleaning member makes the relative movement.

An image forming apparatus includes: as a conveyance path to convey an object formed with an image by an image former, a bent conveyance path exhibiting a bent shape; and a straight conveyance path connected to a downstream side of the bent conveyance path and exhibiting a straight shape, wherein the bent conveyance path and the straight conveyance path each include: a pair of guide parts facing each other to form the bent conveyance path and the straight conveyance path; and a plurality of friction reducing parts that are arranged in a conveyance direction on one of a pair of the guide part and are able to abut with an image forming surface of the object conveyed between a pair of the guide parts.

An image forming apparatus comprising includes an image carrying member including a movable surface to include a toner image; a transfer roller to form a transfer nip between the transfer roller and the movable surface of the image carrying member, to move position in a direction in correspondence to a thickness of a print medium to intersect a direction of introduction of the print medium into the transfer nip, and to receive a transfer bias voltage to transfer the toner image from the movable surface of the image carrying member to the print medium; and a movement guide structure to guide the print medium toward the transfer nip, and to move in synchronization with the movement of the position of the transfer roller to change a gap between an end of the movement guide structure facing the image carrying member and the image carrying member.

A sheet conveyance apparatus includes first and second abutment surfaces in contact a leading edge of a conveyed sheet before the sheet is nipped by a conveyance portion, which nips the sheet while the first and second abutment members are moving from respective standby positions together with first and second rotary members by being pressed by the leading edge. The first and second rotary members are in contact with the sheet being conveyed by the second conveyance portion after the leading edge of the sheet passes through the first abutment surface, the first rotary member, and the second abutment surface, and the second rotary member, and the first and second abutment members move toward standby positions by urging members after a trailing edge of the sheet passing through the first and second rotary members.

An image forming apparatus includes a housing, a sheet conveyor, a sheet stacker, and circuitry. The sheet conveyor is configured to convey a sheet on which liquid is applied. The sheet stacker is configured to stack the sheet conveyed by the sheet conveyor. The circuitry is configured to control conveyance of the sheet. The circuitry is configured to cause the sheet conveyor to expose the sheet on which the liquid is applied, to an outside of the housing, and convey the sheet to the sheet stacker.
