Abstract
An image-forming device includes a body frame, a belt unit, and a process cartridge. The belt unit includes a belt unit main frame having a first main end portion and a second main end portion in a first direction, a first roller disposed at the first main end portion, a second roller disposed at the second main end portion, a belt mounted around the first roller and the second roller, and a handle part disposed at the first main end portion and has a contacting part. The process cartridge includes a photosensitive drum having a photosensitive surface opposed to the belt in a second direction, and a casing accommodating the photosensitive drum and having a contacted part. The contacting part contacts the contacted part to prevent the photosensitive surface from contacting the belt unit when the process cartridge is mounted in the body frame.
