Definitions
- the sheet supply tray 3 and the ejection tray 8 are mounted on shafts 3a, 8a, respectively within the system body 16 for pivotal movements in directions b in Fig. 2, and for pivotal movements around shafts 3b, 8b in directions c in Fig. 2.
- Locking projections 3c, 8c are formed on free ends of the trays 3, 8 at both sides thereof, respectively. These projections can be fitted into locking recesses 1b2 formed in an upper surface of the original hold-down plate 1b.
- the feed member 12b1 has a lock projection 12b4 at its one longitudinal end, which projection is rotatably fitted into a slot 12b5 formed in the arm member 12b2.
- the arm member 12b2 is rotatably mounted on the upper frame 14 via a shaft 12b3 and is connected to an arm (not shown) disposed outside the toner reservoir 12a.
- a drive transmitting means is connected to the feed members 12b1 so that, when the process cartridge B is mounted within the image forming system A, the driving force from the image forming system is transmitted to the feed members to swing the arm member 12b2 around the shaft 12b3 by a predetermined angle.
- the feed members 12b1 and the arm member 12b2 may be integrally formed from resin such as polypropylene, polyamide or the like so that they can be folded at a connecting portion therebetween.
- the non-magnetic toner adhered to the developing sleeve 12d enters into an abutment area between the developing blade 12e and the developing sleeve 12d to form the thin toner layer on the developing sleeve, and the toner is frictionally charged by the sliding contact between the toner and the developing sleeve with the polarity sufficiently to develop the electrostatic latent image.
- the toner remains on the developing sleeve 12d, the remaining toner is mixed with the new toner fed to the developing sleeve 12d and is fed to the abutment area between the developing sleeve and the developing blade 12e.
- the developing bias contact 18b is also attached to the bearing member 26, and, when the bearing member 26 is attached to the developing sleeve 12d, the bias contact 18b is contacted with a conductive member 18d contacting the inner surface of the developing sleeve 12d.
- the tear tape 27 can easily be exposed from the process cartridge in assembling the upper and lower frames 14, 15.
- the gripper portions 14f, 15k are utilized when the process cartridge B is mounted within the image forming system.
- the operator forgets to remove the tear tape 27 before the process cartridge is mounted within the image forming system, since he must grip the gripper portions in mounting the process cartridge, he will know the exsistence of the non-removed tear tape 27.
- the color of the tear tape 27 is clearly differentiated from the color of the frames 14, 15 (for example, if the frames are black, a white or yellow tear tape 27 is used), the noticeability is improved, thus reducing the missing of the removal of the tear tape.
- the assembling and shipping line for the process cartridge B will be explained with reference to Fig. 39A.
- the various parts are assembled in the lower frame 15, and then, the lower frame into which the various parts are incorporated is checked (for example, the positional relation between the photosensitive drum 9 and the developing sleeve 12d is checked).
- the lower frame 15 is interconnected to the upper frame 14 within which the patrs such as the charger roller 10 are assembled, thereby forming the process cartridge B.
- the total check of the process cartridge B is effected, and then the process cartridge is shipped.
- the assembling and shipping line is very simple.
- positioning projections 15m are formed on the lower frame 15 to which the photosensitive drum 9 is attached, in the vicinity of both longitudinal ends of the frame. As shown in Fig. 5, when the upper and lower frames 14, 15 are interconnected, these projections 15m protrude upwardly through holes 14g formed in the upper frame 14.
- the process cartridge B is mounted within the image forming system A, the distance between the lens array 1c2 in the lens unit 1c and the photosensitive drum 9 mounted on the lower frame 15 is accurately determined, so that the light image optically read from the original 2 can be accurately illuminated onto the photosensitive drum 9 via the lens array 1c2.
- the charger roller 10 is mounted on the upper frame 14 other than the lower frame 15 on which the photosensitive drum 9, developing sleeve 12d and cleaning means 13 are mounted, the upper frame 14 separated from the lower frame 15 can easily be cleaned.
