PURPOSE:To obtain a stable copied image immediately after manufacture of an electrophotographic receptor, by removing residual solvent contained in the electrophotographic receptor using the solvent in its manufacture process through high frequency wave heating, and drying the receptor efficiently in a short time. CONSTITUTION:A solvent is removed from an electrophotographic receptor contg. the residual solvent prepared by a manufacture process using the solvent, such as formation of a photoconductive layer and an insulating resin layer, and at that time 0.1-200GHz high frequency wave heating is utilized to dry the receptor and remove the solvent. For example, a photosensitive layer 2 contg. water and ethanol formed on a support drum 3 is subjected to irradiation of 10GHz high-frequency waves generated from its oscillator 4 for 5min and then, 1GHz waves for 1min, while the layer 2 is rotated, thus permitting the obtained photosensitive drum 1 to form a sharp image free from unevenness, and drying to be finished very efficiently in a short time. High frequency waves corresponding to the intrinsic frequency of the used solvent molecule are selected. |
