Abstract
A copying machine including a specifying unit movable along the document support for specifying a particular point and operable to divide an area of the document support into a first area, delimited between the exposure start position to the particular point, and a second area delimited between the particular point and the exposure terminating position; a first developing unit with a mass of developing material of first color therein and operable to develop an electrostatic latent image into a visible powder image, a second developing unit with a mass of developing material of second color therein and operable to develop the electrostatic latent image into a visible powder image, and an erasing unit for erasing the electrostatic latent image before the electrostatic latent image is developed by one of the first and second developing unit; a mode specifying unit for specifying relative to the first and second areas one of a first mode in which the electrostatic latent image on the photosensitive medium is developed into the visible powder image of first color with the use of the first developing unit, a second mode in which the electrostatic latent image on the photosensitive medium is developed into the visible powder image of second color with the use of the second developing unit, and a third mode in which the electrostatic latent image on the photosensitive medium is erased with the use of the erasing unit.
