Abstract
PURPOSE:To enable superposed copying or partly removed copying to be performed simply by providing the two recording means for forming electrostatic latent images by charging photoreceptor thereby making the charging polarities of one of recording means changeable to positive and negative. CONSTITUTION:This is the apparatus of performing superposed copying or partily removed copying with a pin tube 13 being a second recording means to a photosensitive drum 8 having been formed with latent images with a first recording means by providing the pin tube 13 being the second recording means of recording the picture signals having been received on the photosensitive drum 8 besides the first recording means of exposing an original 2 with the optical system including a light source 3 and mirrors 4 thru 7, etc. and forming the latent images on the photosensitive drum 8, whereby the potentials to be applied to the pins of the pin tube 13 are changed over to positive or negative, whereby the superposed copying or partly removed copying may be performed freely and easily.
