る除電光源の取付け装置。 An upper opening is formed in the upper part of the housing, a cartridge in which a photoreceptor is rotatably supported on a frame is removably installed in the housing through the upper opening, and paper is placed above the photoreceptor. In an electrophotographic apparatus having a sheet conveyance path for conveying paper, a static eliminating light source for removing residual potential of the photoreceptor is movably supported on a housing so as to be able to move toward and away from the photoreceptor, and A biasing means for biasing the light source in a direction away from the photoconductor is provided, and when the cartridge is installed in the housing, the charge eliminating light source is pushed by the cartridge to bias the static eliminating light source. 1. A mounting device for a static elimination light source in an electrophotographic apparatus, characterized in that a pushed member is provided for approaching the photoreceptor against the elastic force of the electrophotographic apparatus.
