PURPOSE:To the titled body having improved humidity dependency by incorporating carboxylate, phosphate, borate or sulfate in an undercoating layer. CONSTITUTION:The undercoating layer 13 and the photosensitive layer 15 are mounted on a conductive substrate body 11. The undercoating layer 13 is formed by dispersing the carboxylate, the phosphate, the borate or the sulfate in a resin. The carboxylic acid is exemplified by an aromatic hydrocarbon carboxylic acid such as 1-naphthalene carboxylic acid, p-amino benzoic acid, etc., or a derivative thereof, an aliphatic hydrocarbon carboxylic acid such as stearic acid, acetic acid or acetylene dicarboxylic acid, etc., or a derivative thereof. The phosphoric acid is exemplified by the phosphate such as 1-naphthyl phosphoric acid or phosphoric acid, polyphosphoric acid, etc., or a derivative thereof. The boric acid is exemplified by boric acid or meta boric acid, etc. The sulfuric acid is exemplified by sulfuric acid, sulfurous acid or thiosulfuric acid etc. The salt is exemplified by an alkaline metal salt such as lithium, potassium, sodium salt, etc., and an ammonium salt.
