Abstract
A cleaner unit for an electrophotographic copying machine including a scraper blade in contact with the surface of a photoreceptive drum and a container for storing toner stripped from the surface of the photoreceptive drum by the scraper blade. The configuration of the cleaner includes an aperture in the container provided in a position above the bottom surface of the cleaner unit, a conveyer member which is provided inside the cleaner unit and is capable of reciprocating between the aperture of the container and an inlet aperture of the cleaner unit adjacent the photoreceptive drum and a guide plate that causes the conveyer member to move its tip into contact with the bottom surface of the cleaner unit when the conveyer member moves in the direction of the aperture of the container, and conversely, it prevents the tip end of the conveyer member from coming into contact with the bottom surface of the cleaner unit when the conveyer member moves in the direction of the inlet aperture adjacent the photoreceptive drum.
