Cleaning method and device for electronic camera photoreceptor matrix

The present invention relates to an electrophotographic photoreceptor, a cleaning method and a substrate cleaning apparatus. Method for the purposes of cleaning the substrate (4): a step for degreasing and cleaning with a washing solution (9), rinsing and drying step with rinsing liquid (12). Wherein the washing liquid (9) used in the degreasing step is washed with a temperature of 20 ℃ ~ 90 ℃ ionized alkaline water. Cleaning apparatus comprising: a cleaning tank (1), with an alkali ion water (9) for cleaning a substrate (4); a heater (H 1 ), heating the alkali ion water (9), so that at a temperature of 20 ℃ ~ 90 ℃; rinse tank (2), containing rinsing liquid (12), for rinsing the cleaned substrate (4); a heating tank (3), with warm water (13), for heating the rinsed substrate (4); a holder (14) for holding the substrate (4); lifter (7), the base body (4) and vertically so as to swing. Degrease with a small amount of energy of the substrate surface without damaging the electrophotographic photoreceptor substrate.
