摘要： An image forming apparatus is provided which includes a main body, and a belt unit removable from the main body. The belt unit includes a belt extending between a drive roller and a driven roller and configured to rotate such that a recording medium is fed in a feeding direction. The apparatus further includes a feeding device that feeds the recording medium to the belt, and a positioning section including an engaging portion and an engaged portion, the positioning section being configured to position the belt unit when the engaging portion engages the engaged portion. Also, an urging member is provided that urges the belt unit and causes a pressing force to be applied between the engaging portion and the engaged portion. An urging direction of the urging member has a component in the feeding direction.

摘要： 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 from contacting the belt unit when the process cartridge is mounted in the body frame.
