PURPOSE: To prevent drop in surface resistance due to adhesion of paper dust, etc., on a surface when an electrophotographic photoconductor body is used repeatedly to prevent flow of image.
CONSTITUTION: A charge carrying layer, a charge generating layer, and a protection layer are accumulated in that order on a conductive supporting body. In the protection layer, heat-cure silicon resin, urethane elastomer, and hydrophobic silica are contained. Also the surface roughness of the protection layer is over 0.01μm and below 0.5μm in mean roughness relative to the centerline. Thus an electrophotographic photoconductor body can be obtained which is sensitive by positive charging, stable against temperature and humidity, not provided with image flow due to drop in surface resistance under high temperature and humidity produced especially by the adhesives on a surface such as paper dust, etc., after it is used repeatedly, hard and strong in film even if the protection layer is thin, and excellent in wear-resistance and durability.
