ABSTRACT:
The invention is directed to an arrangement for removal of electrical charge from non-image bearing portions of a photosensitive medium in a photocopying machine, in which radiation of light for removal of electrical charge from portions of the medium which are not required for production of an image, when photocopies at reduced magnification are produced, for example, is made the same as or closely similar to the intensity of light for effecting production of an image, whereby unwanted adhesion of developer material to the medium is avoided, and at the same time, since all portions of the medium are always exposed to generally the same intensity of radiation, characteristics of different portions of the medium are maintained constant even after prolonged use thereof.
