When assembled, the protruding shaft member is disposed at the two ends of the photosensitive drum, and the photosensitive drum is placed in the toner cartridge. After the predetermined position of the body, the photosensitive drum is positioned by being disposed on both sides of the casing by the two side covers, wherein the side cover has a pivoting tube for inserting the shaft member, whereby the photosensitive drum can have the 2 axes The piece rotates for the axis. Since the two side cover systems are ultrasonically welded to the casing, the disassembly is not easy. Therefore, when the photosensitive drum is to be replaced, at least one of the shaft members must be broken, and the photosensitive drum can be taken out. When installing a new photosensitive drum, as shown in the first figure, a sleeve 2 is first installed at one end of the photosensitive drum i, the sleeve 2 has a shaft hole 3, and the four-card slot 4 is located at the periphery of the shaft hole 3. Then, the photosensitive drum is placed together with the sleeve 2 into a casing (not shown) of the toner cartridge. At this time, the shaft hole 3 of the sleeve 2 corresponds to the pivoting pipe of the one side cover (Fig. In the end, the shaft member 5 is inserted into the shaft hole 3 of the sleeve 2 via the pivot tube, and the shaft member 5 is engaged with the sleeve 2 by using the four hooks 6, and the shaft member is married. The four ribs 7 are received in the four slots 4 of the sleeve 2, so that the sleeve 2 can be rotated together with the shaft member, thus completing the assembly of the new photosensitive drum. Both the conventional sleeve 2 and the shaft member 5 are formed by plastic injection molding, since the 20-axis member 5 has four convex ribs 7, and the sleeve 2 has four card slots 4, which are manufactured by the prior art due to the problem of demolding technology. It can not be overcome, so that the sleeve 2 and the shaft member 5 are often unable to achieve a good degree of eccentricity when the drum is rotated; in addition, the sleeve 2 is round and often due to structural strength. Deformation occurs when it is insufficient, which also affects the rotation of the photosensitive drum. [Disclosed] A support for a photosensitive drum An object of the present invention is to provide a structure which has high structural precision. Another object of the present invention is to provide a structure which has a large structural strength. In order to achieve the foregoing object, the support device provided by the present invention is applied to a photosensitive drum, which comprises a sleeve and a shaft member, and the (four) has an outer wall attached to the inner wall of the photosensitive drum, (4) defining that a shaft engaging portion is disposed on the inner wall, and at least - the rib is located in the shaft; the miscellaneous member has an outer tube accommodated in the (four) view, and a second portion is disposed on the outer tube and The first engaging portion of the sleeve is snapped together, the second connecting portion (four) outer tube extends inwardly, and one tube is disposed in the connecting body = the inner tube is for inserting the rib of the sleeve, thereby The structure of the material is high in accuracy and high in strength.
