    • A photoreceptor including an electroconductive substrate, a photosensitive layer located overlying the electroconductive substrate, and a surface layer located overlying the photosensitive layer, wherein the surface layer is a cross linked surface layer comprising filler particulates on which linear scar is formed along the circumference direction, and the filler particulates form concave portions on a groove formed by the linear scar, and wherein the ten point average roughness Rz along the direction of the rotation axis of the photoreceptor measured on the circumference surface thereof is from 0.17 to 2.00 μm and the average distance Sm of concavities and convexities along the direction of the rotation axis of the photoreceptor measured on the circumference surface thereof is from 20 to 500 μm, and the ten point average roughness Rz along the circumference direction of the photoreceptor measured on the circumference surface thereof is from 0.13 to 0.50 μm and the average distance Sm of concavities and convexities along the circumference direction of the photoreceptor measured on the circumference surface thereof is from 10 to 40 μm.
    • 包含导电性基体的感光体,位于导电性基体上方的感光层和位于感光层上方的表面层,其中,所述表面层为包含填充剂颗粒的交联表面层,沿所述圆周方向形成有线状的痕迹, 并且填料微粒在由线性疤痕形成的凹槽上形成凹部,并且其沿着在其圆周表面上测量的感光体的旋转轴的方向上的十点平均粗糙度Rz为0.17至2.00μm,平均距离 沿其圆周表面测得的感光体的旋转轴方向的凹凸的Sm为20〜500μm,沿圆周面测定的感光体的圆周方向的十点平均粗糙度Rz为 0.13〜0.50μm,平均距离 在其圆周表面上测量的感光体沿着圆周方向的凹凸的Sm为10〜40μm。
