ABSTRACT:
An image-forming device includes: a main device body; a plurality of process cartridges; a fixing unit; a tray; a switchback conveying path; and a reverse conveying unit. The plurality of process cartridges are detachably mounted in the main device body. The process cartridges are arranged in a row in the main device body when the process cartridges are mounted in the main device body. Each process cartridge has an image-carrying member that transfers a developer image carried thereon to a sheet by opposing the sheet. The fixing unit is provided in the main device body and fixes the developer image to the sheet after the image has been transferred thereto. The tray is provided in the main device body and supports the sheet after the developer image has been fixed thereon. The switchback conveying path is provided in the main device body and guides the sheet from the fixing unit to the tray, while switching a conveying direction of the sheet. The reverse conveying unit is disposed in the main device body along the switchback conveying path and reverses the conveying direction of the sheet.
