Abstract

PURPOSE:To control the reproduction and gradation of an image in a relatively simple manner in order to enlarge the range of an original drawing capable of being copied by providing an adjustable unit which adjusts the thickness of developing agent layer to a developing roller such that the agent layer can be suitably selected in accordance with the condition of the original drawing.
