ABSTRACT:
The method for forming an electrostatic image according to the present invention comprises the steps of charging an electrophotographic photoreceptor, which is subjected to dark decay after the charging step, and effecting an exposure by activation light and an imagewise exposure on the electrophotographic photoreceptor. The exposure by activation light is effected prior to the imagewise exposure and in a step including at least a portion of the charging step or dark decay. This causes a remarkable sensitization effect in the electrophotographic photoreceptor, suitably adapted for use in an electrophotographic copying machine of a repeated transfer type.
