ABSTRACT:
A transfer type electrostatic copying apparatus employs a photosensitive member of organic photoconductive material and one-component developing toner. There is provided a charge eraser lamp for erasing or removing a residual charge remaining on the surface of the photosensitive member after the transfer process. The charge eraser lamp has spectral characteristic so as to not emit ultraviolet rays and near ultraviolet rays, whereby any reduction of density is avoided and improved quality of the copied image is achieved.
