PROBLEM TO BE SOLVED: To make positioning accuracy of a process cartridge to an image forming device main body possible to be improved. SOLUTION: This image forming device is allowed, to make a bonded surface 156 of a cleaning frame body cap 13p and the cleaning frame main body 13q, the surface of the cartridge control contact part 13e, and a positioning center P of the cap 13p and the main body 13q so as to pass through the same point in the case of viewing it from a side plane. In such a manner, the device is free from manufacturing error arising as a result of the contact plane located parting from the positioning part, free from dimensional error along the contact plane between a first frame body and a second frame body, and free from the manufacturing error occurring as a result of a wide gap between an extension plane on a control contact part and the positioning part, in consequence that the extension plane on the control part and the positioning part are crossing the same point as above. Accordingly, the position of the control contact part on the first frame body is accurately fixed with respect to the first frame body. Therefore, the positional accuracy of a posture of the process cartridge with regard to the image forming device main body can be improved.
