Abstract

PURPOSE:To form characters or the like with different colors by specifying the optional range of an original, erasing images on the inside or outside of a specified range and generating patterns such as characters. CONSTITUTION:When a black original is set up on an original platen, a black original specifying key and a red character writing specifying key are depressed and a red character writing specifying mode is set up in a main processor group 71, an exposing lamp 4 lights up and normal copying operation is executed. Then, a driving unit is operated, paper on which the black original picture is formed is sent again to a photosensitive drum and the lighting of light emitting elements is controlled by an erasing array 150 in accordance with the specified range. Namely, the light emitting elements in the specified range are turned off in accordance with data stored in a pattern memory 170. At that time, the lamp 4 is also turned off and exposing scanning of the original is not executed. Thereby, the surface electric charge of the drum is left only in the specified range and erased in the other part. A electrostatic latent image formed on the drum is developed with red toner and transferred, so that numerals, characters, codes, etc. are formed and fixed on the specified range of the paper.
