    • PROBLEM TO BE SOLVED: To provide a method of producing solid body having depressed portions on its surface.
      SOLUTION: The method of producing the solid body having depressed portions on its surface includes using a solution containing a solvent A, a solvent B, a solvent C and a polymer compound, where the solvent B is a hydrophobic solvent, the solvent A is a hydrophilic solvent having a boiling point not lower than the boiling point of the solvent B, and the solvent C is a non-hydrophobic solvent having a boiling point lower than the boiling point of the solvent B, and the contents of the solvent A, solvent B and solvent C satisfy the following (1)-(5) conditions; and solidifying the solution while forming the depressed portions on the surface of the solution by dew condensation in a process of evaporating the solvents included in the solution. The condition (1): the content of the solvent A is 0.1-25.0 mass%, the condition (2): the content of the solvent B is larger than the content of the solvent A, the condition (3): the content of the solvent B is 5.0-49.9 mass%, the condition (4): the content of the solvent C is 50.0-94.9 mass%, and the condition (5): the total content of the solvents A, B, C is 90.0 mass% or more.

    • PURPOSE:To obtain a sharp image superior in contrast, by forming a low resistance protective layer on an interlayer containing an organic polymer as a main component, formed on the photoconductive layer of a photoreceptor. CONSTITUTION:A photoconductive layer 3 is formed on a conductive substrate 4 made of aluminum or the like by vapor depositing Se, Se-Te alloy, Se-As alloy, or the like. An interlayer 2 having a function as an adhesive layer between the photoconductive layer 3 and a protective layer 1 besides a role as a barrier is formed on the layer 3 in
    • 目的:通过在含有有机聚合物作为主要成分的中间层上形成低电阻保护层,形成感光体的光电导层,从而获得较好的对比度。 构成:通过气相沉积Se,Se-Te合金,Se-As合金等,在由铝等制成的导电基板4上形成光电导层3。 使用环氧树脂,聚酯,聚酰胺,有机硅树脂等,在层间3上形成除了作为屏障的作用之外,在光导电层3和保护层1之间具有粘合层的功能的中间层2 < 类似。 此外,在中间层2上形成由包含二茂铁的聚碳酸酯树脂等制成的低电阻保护层1,以获得所需的电子照相受体。
