ABSTRACT:
Copying apparatus is provided in which outline copying for only a designated area of an original image can be easily selected. An area for the outline copying can be designated and images inside and outside the designated area can be copied in different colors. The arrangement includes a plurality of keys for designating an area of an original image to be copied and a scorotron charger for causing a potential in areas other than the outline portions of an electrostatic latent image, formed on a photoreceptor drum, to be substantially equal to a potential in an area containing the image. An eraser unit is provided for erasing the charge in an area where development is not required and a developing device develops the electrostatic latent image. A transfer charger is provided for transferring the image developed by the developing device onto copying paper. When an area of the original images designated and an outline image forming mode is selected by the operator of the machine, two copy operations are performed to composite an outlined image formed inside or outside the designated area and a normal image formed in the area which does not include the outline image so that a composite image is copied onto the copy paper.
