Abstract

PURPOSE:To uniformize an electric conductivity and to eliminate the possibility of contaminating a photosensitive body by coating the surface of a roll with a conductive resin layer consisting of a resin compsn. which is essentially composed of N-methylmethoxylated nylon set at 20-40% rate of ethyl methoxylation and is subjected partly to a crosslinking treatment by an org. acid, etc. CONSTITUTION:A elastic conductive layer 12a is formed via an adhesive agent layer on the outside peripheral face of a metallic shaft 10 and the conductive resin layer 11 is formed on the surface thereof. The conducitve resin layer 11 is formed by dissolving the N-methylmethoxylated nylon having the rate of methylmethoxylation within the 20-40% range in a solvent such as solvent mixture composed of methanol and toluene to prepare a resin soln., and adding a crosslinking agent such as citric acid thereto, then coating the soln. on the outside peripheral face of the elastic conductive layer 12 and curing the coating by drying and further, effecting a crosslinking reaction at a high temp. of about 150 deg.C. The crosslinking agent is selected from at least either of an org. acid and inorg. acid as well as epoxy compd. and melamine compd.
