Abstract An image forming apparatus comprises an apparatus body having a guide rail and a print cartridge movable along the guide rail, in which the guide rail has an engaging portion, the print cartridge includes a holder member and a cover for covering the holder member, the cover having a notched portion and the holder member having an engagement portion which is adapted to be pushed so as to be engaged with the engaging portion of the guide rail, the holder member having an operating portion which is responsive to the engagement of the engagement portion with the engaging portion so as to be moved into and out of the cover through said notched portion of the cover. Since the print cartridge slides along the guide rail provided on the apparatus body, and therefore the print cartridge can be easily attached to and detached from the apparatus body. And besides, when the print cartridge is pushed into the predetermined position in the apparatus body, the engagement portion of the holder member is engaged with the engaging portion of the guide rail so that the print cartridge is prevented from withdrawing from the apparatus body due to vibration or the like during the operation.
An image forming apparatus comprising an apparatus body having a guide rail; and a print cartridge movable along said guide rail; said guide rail having a first engaging portion; said print cartridge including a holder member and a cover covering said holder member; said cover having a opening portion; and said holder member having a second engagement portion which is adapted to be pushed so as to be engaged with said first engaging portion, and an operating portion which is responsive to the engagement of said second engagement portion with said first engaging portion so as to be moved into and out of said cover through said opening portion of said cover.
