Description of the Related Art In an image forming apparatus, it is necessary to wipe the residual toner on the photoconductor with a cleaning blade after transferring the developed image formed on the photoconductor to a transfer sheet. One side of the conventional cleaning device is shown in FIG.
On both inner side surfaces 51 of the waste toner container 50 facing the outer peripheral surface of the photoconductor, both ends of a support member 52 urged in a return direction away from the photoconductor by a return spring (not shown) are rotated by a support shaft 53. A cleaning blade 54, which is attached movably, is fixed to the waste toner container 50 in contact with the outer peripheral surface of the photosensitive member, and the supporting member 52 is pressed toward the photosensitive member by a pressing mechanism (not shown) to move the cleaning blade 54 to the photosensitive member. Is pressed against the outer circumference of. The leakage of the residual toner from between the inner side surfaces 51 of the waste toner container 50 is prevented by the seal member 5.
It is prevented by 5.

されているように、シール部材の表面に低摩擦部材を設
けても同様な欠点が存するものである。Since the support member 52 elastically contacts the seal member 55, in order to separate the support member 52 from the photosensitive member, the force of the return spring for urging the support member 52 is increased. Otherwise, the support member 52 cannot be rotated in the direction away from the photoconductor. Accordingly, the support member 52 cannot be rotated toward the photoconductor unless the pressing force of the pressing mechanism is increased against the return force of the return spring. As a result, the pressing mechanism that presses the support member 52 toward the photoconductor becomes large. Further, since the seal member 55 is pressed against the outer peripheral surface of the photoconductor and is adhered to the waste toner container 50 and rubbed against the support member 52,
When the support member 55 is rotated toward the photoconductor, the seal member 55 is sandwiched between the photoconductor and the cleaning blade 54, so that both ends of the cleaning blade cannot be brought into close contact with the photoconductor. Therefore, there is a drawback that the residual toner on the photoconductor cannot be wiped cleanly. Such a defect is caused by the sealing member 55.
Is caused to be fixed to the waste toner container 50. Therefore, even if a low-friction member is provided on the surface of the seal member, as described in JP-A-59-15274, the same effect can be obtained. There are drawbacks.

The cleaning blade and the seal member can be brought into contact with the image carrier substantially at the same time when they are brought close to the carrier.
It is possible to prevent the seal member from being caught between the cleaning blade and the photoconductor, and to ensure that the cleaning blade is brought into contact with the image carrier over the entire length. In particular, the seal member is a thin film low friction member. Is integrally provided, it is possible to reduce the frictional force between the cleaning blade and the inner surface of the toner container when the cleaning blade is attached. The distortion of the cleaning blade can be prevented and the cleaning blade can be brought into uniform contact with the image carrier.

FIG. 2 is a vertical cross-sectional side view showing the internal structure of the image forming apparatus. In the figure, 1 is a photoconductor as an image carrier, and the outer peripheral surface of the photoconductor 1 is a charger for charging the outer periphery of the photoconductor 1. 2, an exposure optical system 3 for forming an electrostatic latent image by exposing the charged portion of the photoconductor 1 charged by the charger 2, a developing device 4 for developing the electrostatic latent image, and a roller 5 for feeding the sheet. A transfer device 7 for transferring the developed image (toner image) on the photoconductor 1 to the transfer sheet 6 to be transferred, and a waste toner container 8 are sequentially arranged. A support member 10 for holding a cleaning blade 9 along the longitudinal direction of the photoconductor 1 is movably held in the waste toner container 8 in a direction approaching and moving away from the photoconductor 1. The cleaning brush 11 that contacts the outer peripheral surface of the is rotatably held.

1 is an enlarged plan view showing one side of the cleaning blade 9 and the support member 10. As is apparent from FIG. 1, both side ends of the support member 10 are formed of a soft material such as urethane foam. The sealing members 12 are adhered, and polyester mylar 13 as a low friction member is adhered to the outer surface of these sealing members 12 or both inner surfaces 14 of the waste toner container 8.

ができる。In such a structure, the cleaning blade 9 is moved away from or pressed against the photoconductor 1 by moving the support member 10 in the direction away from or approaching the photoconductor 1, but the seal member 12 is Support member 10
Since the Mylar 13 having a low coefficient of friction is interposed between the seal member 12 and the inner surface 14 of the waste toner container 8, the frictional resistance received by the support member 10 can be made extremely small. Further, since the seal member 12 moves together with the support member 10 and the cleaning blade 9 to come into contact with and separate from the photosensitive member 1 integrally, the cleaning blade 9
The relative position with respect to does not change. Therefore, when the support member 10 is moved to the photoconductor 1 side, the cleaning blade 9 and the seal member 12 can be brought into contact with the photoconductor 1 substantially at the same time, and therefore, between the photoconductor 1 and the cleaning blade 9. The sealing member 12 does not get caught, and the cleaning blade 9 can be pressed against the photoconductor 1 over the entire length to reliably wipe off the residual toner.
