    Abstract: Cylindrical base bodies for photosensitive drums according to first to fifth inventions are each formed by using a conductive resin composition containing a resin base material and a conductive agent dispersed in the resin base material. The base body of the first invention is characterized in that a dimensional accuracy is enhanced by using a mixture of a polyamide and a low water absorption resin as the conductive resin composition. The base body of the second invention is characterized in that a uniform and stable conductivity is obtained by using carbon black having a specific DBP oil absorption amount as the conductive agent. The base bodies of the third and fourth inventions are characterized in that a surface smoothness and a strength are enhanced by using a micro-spherical material or a flaked shape material, or a fibrous inorganic material having a specific fiber length and a specific fiber diameter as an inorganic filler for reinforcement added to the conductive resin composition. The base body of the fifth invention is characterized in that occurrence of charging noise is suppressed by using a composition having a specific tan null as the conductive resin composition.

    Abstract: An axially extending tubular composite member having a plurality of plies and extending along a longitudinal axis has at least three plies with selectively structured fiber components in each ply and an internal impact resistant beam having a C-shaped or U-shaped cross section positioned between two of the plies. Typically an inner ply has at least one biaxial fiber component, an intermediate ply has at least an axial fiber component that typically is combined with two further fibers to form a triaxial fiber component. Another ply typically has a woven fiber component. A further ply having a biaxial component either replaces the ply of woven fiber or is disposed beneath it over the intermediate ply. A surface veil having fiber and an excess of resin material typically covers at least the innermost or outermost surface of the composite member. The impact resistant member is constructed from an impact resistant material such as ABS plastic, and is typically positioned between the intermediate ply and the exterior ply.
