場合に限られていた。2. Description of the Related Art Conventionally, an aluminum die cast product or a resin molded product has been generally used as an end supporting member for a cylindrical electrophotographic photosensitive member, but the resin molded product has a relatively low manufacturing cost. Therefore, it has come to occupy most of the use as an end support member. When the end support member is an aluminum die cast, the end support member and the end of the cylindrical substrate may be fitted and fixed only by press fitting, but in the case of a resin molded product. In general, a method of fitting and adhering the end supporting member and the end of the cylindrical substrate with an adhesive is generally used. However, in bonding the end supporting member made of a resin molded product and the end of the cylindrical substrate,
Generally, the adhesive force on the end supporting member side is inferior to that on the cylindrical substrate side. Therefore, for the purpose of improving the adhesive force with respect to the torque on the side of the end supporting member, the outer peripheral surface of the hollow cylindrical structure of the end supporting member fitted with the inner peripheral surface of the end of the cylindrical base has a depth of 0.5 mm. It has been practiced to provide a few or more than a dozen or less axial grooves in the cylinder in the circumferential direction. In this case, it is considered that the improvement of the adhesive force with respect to the torque is due to the anchor effect being exerted by filling the groove on the outer peripheral surface of the hollow cylindrical structure of the end support member when the adhesive solidifies. However, such an anchor effect can be expected only in the case of an adhesive having a high viscosity such as an epoxy adhesive and having a small volume shrinkage even after solidification.

あった。On the other hand, an adhesive having a low viscosity of, for example, about 1000 cps or less has been desired to be used because of high efficiency of the bonding work. In that case, thick coating at the time of applying the adhesive is required. In addition, it is difficult to fill the groove because it has a relatively large volume shrinkage upon solidification, and it has been difficult to increase the adhesive force against torque. Furthermore,
The end support member having such a shape is fitted to the end of the cylindrical base body,
The cylindrical electrophotographic photosensitive member formed by adhesion has a problem that peeling of the adhesion between the end support member and the cylindrical substrate is likely to occur in a low temperature or high temperature environment such as during transportation.

る。As the end supporting member which is adhesively fitted to the cylindrical substrate, a resin member or a metal member can be used.
There is no particular limitation when fitting and adhering after coating and drying, but when drying the image holding member after fitting and adhering, a material with a high heat distortion temperature is used as the end support member so that the dimensional accuracy does not decrease in the drying process. It is necessary to choose. Further, it is necessary that the end supporting member has an electrically conductive member attached thereto or that the end supporting member itself has conductivity. That is, it is necessary to make the cylindrical portion of the cylindrical base body and the rotating shaft of the cylindrical base body electrically conductive. For that purpose, a conductive member having a spring property such as phosphor bronze is attached to the end support member. , The rotation shaft and the inner peripheral surface of the cylindrical substrate are connected, or the end supporting member itself is formed of a conductive material. The latter is preferable in order to simplify the fitting process. As the conductive material, for example, a conductive resin such as polybutylene terephthalate, polycarbonate, or ABS resin is mixed with conductive powder such as conductive carbon or metal powder. The ones that have been done are listed.
