Examples
Embodiment 1 to 9
[0182] The belts for electrophotography according to Examples 1 to 9 each have a distinct discoloration due to the presence of the component (e) in the base layer and the components (a) and (b) in the curable composition by the above-mentioned mechanism. The surface is roughened to a surface roughness Rzjis of 0.3 to 0.7 μm by agglomeration of impurities.
[0183] Further, the adhesiveness with other members was low both at the initial stage and after durability, and the number of abnormal points (graining) was small.
[0184] The average primary particle diameters of the inorganic oxide particles and conductive metal oxide particles forming heteroaggregates are shown in Table 3 above.
Embodiment 10
[0186] The belt for electrophotography according to Example 10 has significant hetero-aggregation due to the presence of component (e) in the base layer and components (a) and (b) in the curable composition by the above mechanism. Roughen the surface to a surface roughness Rzjis of 0.65 μm.
[0187] Further, the adhesiveness with other members was low both at the initial stage and after durability, and the number of abnormal points (graining) was small.
[0188] The average primary particle diameters of the inorganic oxide (silicon dioxide) particles and the conductive metal oxide (zinc antimonate) particles forming heteroaggregates are shown in Table 3 above.
[0189] In the present example, since the component (e) is auxiliary added to the curable composition 8, the roughness of the surface layer is greater than in Example 1.
Embodiment 11
[0191] The belt for electrophotography according to Example 11 has significant hetero-aggregation due to the presence of component (e) in the base layer and components (a) and (b) in the curable composition by the above mechanism. The surface is roughened to a surface roughness Rzjis of 0.30 μm.
[0192] Further, the adhesiveness with other members was low both at the initial stage and after durability, and the number of abnormal points (graining) was small.
[0193] The average primary particle diameters of the inorganic oxide (silicon dioxide) particles and the conductive metal oxide (zinc antimonate) particles forming heteroaggregates are shown in Table 3 above.
[0194] In this example, compared with Examples 1 to 10, the addition amount of component (a) and component (b) in the curable composition was reduced, and the roughness Rzjis of the surface layer was 0.3 μm.
