Abstract

Abstract A method for producing an image forming member having a deposited layer with photoconductivity formed on a support by introducing a starting material in gaseous state into a deposition chamber which is reduced to a desired pressure and exciting discharging in the gas atmosphere of said starting material, comprises constituting at least a part of said deposited layer of a layer (A) comprising silicon atoms, carbon atoms and hydrogen atoms, said layer (A) being formed of at least one of the compounds represented by the formula: RmSinH2n+2-m (I) where R is an alkyl having 1 to 15 carbon atoms, m is an integer of 1 to 15, n is an integer of 1 to 5, and m and n satisfy the relation of 2n+2>m.
