Patent ID: 7020416

Claim:
An image forming apparatus comprising: an image forming apparatus main body; a process frame body including at least a photoconductive body, image forming means for forming an electrostatic latent image on a surface of the photoconductive body, and a frame main body for holding the photoconductive body and the image forming means; and a development device including at least development means for developing the electrostatic latent image using toner, toner supply means for feeding toner to the development means, and a development device main body for holding the development means and the toner supply means, the process frame body and the development device being attachable to and detachable from the image forming apparatus main body in a predetermined order, the process frame body and the development device each having attachment/detachment order controlling means for preventing the process frame body and the development device from being attached and detached in an order different from the predetermined order; wherein the process frame body further comprises frame securing means which is, in attachment operation, fitted to a certain portion of the apparatus main body to secure the process frame body, and releases, in detachment operation, the fitting to the certain portion by user's operation, and wherein, in cases where the order in which the process frame body and the development device are detached is that first comes the development device, then the process frame body, the attachment/detachment order controlling means of the development device has an inhibitory portion for inhibiting operation of the frame securing means by users, when the process frame body and the development device are attached.
