PURPOSE: To obtain transferred images of a high density repeatedly with good reproducibility at the same density without scumming by incorporating at least one kind of specific compds. into the photopolymn. initiator used in a a photopolymerizable compsn.-contg. layer.

CONSTITUTION: An image forming material is formed by forming the conductive compsn.-contg. layer 2 on a a conductive base consisting of a conductive layer 1A and a base 1B. The electric resistance of the layer 2 is increased by subjecting said layer to imagewise exposing and an electrostatic charge is formed in the exposed region 2A by a corona charger 3 to form an electrostatic latent image 3A. The image is developed by a toner and is transferred. At least one kind of the compds. expressed by the separate formula are incorporated into the photopolymn. initiator used for the layer 2. In the formula, X is a hydrogen atom, alkyl group, aryl group; Y is a fluorine atom, chlorine atom, bromine atom; (n) is 1-2 integer; (a) is 1-2 integer; (l) is 0 or 1. The layer 2 contains the photopolymn. initiator expressed by the separate formula, the photopolymerizable or photocrosslinkable compds. having the ethyleneic unsatd. bond, and a sensitizer, etc., at need.
