ABSTRACT:
A three-color separation electrophotographic color reproduction process which includes primary uniform charge steps, color separation image exposure steps, development steps and transfer steps. The process further includes between each image exposure step and development step a uniform exposure step and a secondary charge step. The secondary charge step is carried out either by DC corona discharge of the same plurality as the primary charge step or by AC corona discharge together with DC corona discharge. The quantity of light of the uniform exposure step and the quantity of charge of the secondary charge step are controlled, to reduce stepwise, as the second and third primary color reproduction proceeds.
