<p>PURPOSE:To share a pressurizing member between the use for fixing a process cartridge and for a rotation body by permitting the process cartridge to be attached to and detached from a device main body in almost the same direction as the optical axis direction of an exposure device. CONSTITUTION:A photoprinter is provided with positioning means 22, 44, and 12 all of which determine a distance between the exposure means 5-10 and the photosensitive body 1 by the contact of a part of the exposure means 5-10 with a part of composing members 1-4 of the process cartridge when the process cartridge C is loaded onto the device main body. The process cartridge C can be attached to and detached from the device main body in almost the same direction A as the optical axis direction of the exposure devices 5-10. Thus, a spring 12 being the positioning means of the exposure devices 5-10 positions and fixes the process cartridge C in the device main body, and also presses a roll which rotates after being brought into press-contact with a photosensitive body such as a transfer roll 24 and electrifying roll 4.</p> |
