Abstract

PURPOSE:To sharply add additional information to copies at low cost by copying an original and additional information in different colors. CONSTITUTION:In order to copy additional information after an original has been copied first time, the resist timing in 2nd copying is accelerated to synthesize additional information at any position in the vertical direction (scanning direction) such as the central part or the far end. When an additional information display device 16 is extended laterally or plural additional information displays are placed and selectively added, information can be added at any position on a copying machine 3. In that case, an original and additional information may overlap, which can be solved by copying additional information in a different color, or by copying with half tone after conditions to process latent images about additional information are changed. Finally information can be added in an original image area. Thus copies including additional information in a different color can be obtained at a moderate cost, and said information can be easily distinguished from an original; therefore easy-to-see copies can be obtained.
