が生じクリーニング性能を損う虞があった。However, as shown in FIG. 1, especially when the cleaning member 2 is attached to the image carrier 1 on the contact surface side of the image carrier 1 and has the adhesive layer 4 adhered to the support plate 3, the image carrier of the cleaning member 2 is carried out. The stress for applying the contact pressure to the body concentrates on the end portion m of the support plate 3 and becomes a force for separating the cleaning member 2 and the image carrier 1. Further, as shown in FIG. 2A, even if the end P of the adhesive surface of the support plate 3 does not have a curvature, it may peel off gradually. Especially, as shown in FIG. With some curvature R, the adhesive bonding point Q point of the adhesive 4 and the end plate bonding point Q of the support plate 3 are different in the longitudinal direction y, and there is a possibility that they may be peeled off more easily than in the case shown in FIG. Also, as shown in FIG.
When the surface opposite to the contact surface of the cleaning member 2 on the image carrier 1 is bonded to the support member 3 via the adhesive layer 4, the contact pressure of the cleaning member 2 on the image carrier 1 is longer than that of the free portion L. It fluctuates greatly depending on the size. Therefore, as shown in the drawing, when the end surface P of the adhesive surface has a curvature R, the length of the free portion L varies depending on the displacement amount a of the cleaning member 2, and the contact pressure varies, which may impair the cleaning performance.

The adhesive layer 30 adheres a. As a result, against the force in the peeling force acting direction u, which was conventionally held at the point P, in the present embodiment, the surface adhesion in the x region is obtained, and the x portion is the surface against the displacement in the u direction. Therefore, stronger adhesion can be obtained. Further, as shown in FIG. 6B, when the curved portion R of the distal end portion 23a of the holding member 23 is effectively used and the adhesive layer 30 is provided between the curved portion R and the blade 21, the bonding is performed.

It may be a curable type. Here, an experimental example was also obtained in which the cured type was more resistant to peeling than the rubber-like adhesive. It is considered that this is because even if the rubber-like adhesive is filled in the P portion, elongation is caused by the external force u although it is slight, and the strength becomes lower than that of the cured type. As the adhesive used for the first and second adhesive layers, either a curable adhesive or a rubber adhesive can be applied, but a curable adhesive is used for the second adhesive layer. Is preferred. In this embodiment, an example is shown in which the second adhesive layer is adhered and held by using a curing type epoxy adhesive.
