j A drum-shaped photosensitive drum 3 serving as a carrier rotates in the direction of arrow R around a shaft 3a, while copying an image of a document 0 on a document table l moving in the direction of arrow X. First, the photosensitive drum 3 is primarily charged by the charger 4. There, when the reflected light of the original image O illuminated by the original illumination lamp L is imaged and exposed by the short focus lens array 2, an electrostatic latent image is formed. When this imaging exposure is completed, the document table 1 moves back. During this time, the blank exposure lamp Q is turned on to illuminate the outside of the image-forming exposure range of the photosensitive drum 3, which is rotating further, to short-circuit and eliminate the primary charge. The formed electrostatic latent image is visualized with toner supplied from the developing device 5. The developed toner image is transferred to a copy paper P sent from a cassette S by a charger 8. The copy paper P is then separated from the photosensitive drum 3 by a charger 9, and the developed toner image thereon is fixed by a fixing device 7 before being discharged outside the machine. On the other hand, the toner remaining on the photosensitive drum 3 is cleaned by a cleaner 14, and the residual charge on the photosensitive drum 3 is short-circuited and eliminated by the irradiation light from the document illumination lamp L.

ある。FIG. 2 is a cross-sectional view illustrating the details inside the process cartridge 17. In FIG. ) is the mounting mechanism for each device attached to each. A rotating shaft 3a of the photosensitive drum 3 is fitted into a bearing 3b. A groove member 65 having a sufficient margin (margin space amount Y) relative to the outer diameter of the bearing 3b is attached to the front and rear frames of the process cartridge 17, and the bearing 3b is placed therein. On the other hand, a holding member 22 of the charger 4 is rotatably supported by a shaft 49 on the front side (and rear side) of the cleaner 14 attached to the front and rear frames of the process cartridge 17 . This charger holding member 22 is fixed with screws 64 to a stage 67 attached to the front and rear frames of the process cartridge 17. In addition, an elastic member 66 is provided in the charger holding member 22.
is fixedly installed and the charger 4 is held in position (shape s in the figure), the bearing 3b in the groove 65 is pressed against one edge of the groove 65 by the elastic member 66, The photosensitive drum 3 is held in place. The elastic member 66, groove 65, and photosensitive drum 3 at this time are shown in the perspective view of FIG.

A rotating lever 42 attached to the front and rear frames of the process cartridge 17 is urged counterclockwise by a spring 43 and presses a protrusion 44 on the front side (and rear side) of the developing device 5. The weight of the developing device 5 from its center of gravity acts as a clockwise force on the support shaft 41, but due to the rotational biasing pressure of the rotating lever 42 and the spring 43, the abutting rollers provided on the outside of the developing sleeve 45 46 comes into contact with the side of the photosensitive drum 3, and the positional relationship between the developing device 5 and the photosensitive drum 3 is maintained constant. Further, a gear 47 (see FIG. 5) attached to the rotating shaft 3a of the photosensitive drum 3 is connected to a gear (not shown) on the developing device 5 side [l! 1 matches.

The pin 26 of the nest plate 25 of the apparatus main body fits into the hole 39 of the rear frame 33 of the process cartridge 17, and the pin 38 of the rear frame 33 fits into the hole 27 of the nest plate 25, respectively. The process cartridge 17 is placed on a holding frame 18, and can be pulled out from the main body of the apparatus by pulling a handle 30 attached to the front of the frame 29.

やギアが感光ドラム3と再接触してしまうこともない。When the rotation lever 42 is turned counterclockwise, the developing device 5 rotates by its own weight about the shaft 41, and is separated from the photosensitive drum 3 and held by the stopper 40. The amount of separation at this time is set to be larger than the amount of free space Y provided in the groove 65. Next, when the screw 64 is removed from the stage 67 and the charger holding member 22 is rotated, the pressing of the elastic member 66 against the bearing 3b is released. Since the groove 65 has enough space for the bearing 3b, the photosensitive drum 3 can be removed after being sufficiently separated from the cleaning blade 69 and scooping sheet 70. In addition, the abutting roller 46
This prevents the gear from coming into contact with the photosensitive drum 3 again.
