According to one embodiment, a sheet conveying device includes a roller, a motor, a clutch, and a torque generator. The roller conveys a sheet. The motor is a driving source. The clutch connects or disconnects drive of the motor with respect to the roller. The torque generator applies a torque to the roller.

A thermal-transfer printing apparatus includes a roll-paper-supplying unit that rotates an image-receiving paper roll and unwinds and winds a roll type of first image-receiving paper, and a print unit that includes a thermal head for heating a thermal transfer sheet and that forms an image by transferring a color material from the thermal transfer sheet to the first image-receiving paper. With the image-receiving paper roll removed, a reverse unit that reverses a sheet type of second image-receiving paper is mountable in a region in which the image-receiving paper roll used to be contained. The print unit forms the image on the first image-receiving paper in a first printing mode in which the image-receiving paper roll is contained in the region, and the print unit forms an image on both surfaces of the second image-receiving paper in a second printing mode in which the reverse unit is mounted on the region.

A recording device includes a recording unit configured to perform recording on a recording target medium, a first conveyance path that is a conveyance path of the recording target medium including an opposite position that faces the recording unit, and conveyance of the recording target medium in a first direction, a second conveyance path being coupled to the first conveyance path at a position downstream of the recording unit in the first direction, the second conveyance path being coupled to the first conveyance path also at a position upstream of the recording unit in the first direction and configured for conveyance of the recording target medium to the first conveyance path with a surface of the recording target medium inverted, and an insertion port configured to enable insertion of a recording target medium as an insertion material to the second conveyance path from outside.

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 includes an image forming unit to form an image on a sheet, a conveyance guide unit, and a conveyance unit. The conveyance guide unit conveys the sheet on which the image is to be formed by the image forming unit. The conveyance unit conveys the sheet toward a first conveyance guide unit. The conveyance guide unit includes an urging member, a rotary member to be urged by the urging member and to rotate while abutting the sheet, a holding unit holding the urging member and the rotary member, and the first conveyance guide unit that is detachably attached to the holding unit to guide the sheet. The first conveyance guide unit includes a pressed portion, and the pressed portion is to be pressed by the sheet conveyed by the conveyance unit and has strength less than strength of the holding unit.

An image forming apparatus includes: as a conveyance to convey an object formed with an image, an upstream-side conveyance path; an intermediate conveyance path connected to a downstream end part of the upstream-side conveyance path via a first bent part; and a downstream-side conveyance path connected to the intermediate conveyance path via a second bent part, wherein the second bent part is bent to a side opposite to the first bent part, on an inner side of a bend of the first bent part, a friction reducing part capable of abutting with the object conveyed in the first bent part is provided, and the intermediate conveyance path includes: a pair of guide parts forming the intermediate conveyance path; and a friction reducing part that is provided on both a pair of the guide parts and is capable of abutting with the object conveyed between a pair of the guide parts.

A medium transport unit includes an upstream route in which a print sheet is transported, a first switchback route, a second switchback route, a first guide route, a second guide route, a guide flap configured to switch the route so that the print sheet in the upstream route is transported either toward the first guide route or toward the second guide route, a first discharge route from which the print sheet in the first switchback route is discharged, a second discharge route from which the print sheet in the second switchback route is discharged, and a downstream route passing between the first switchback route and the second switchback route and having an upstream end connected to a junction of downstream ends of the first discharge route and the second discharge route.
