Abstract
PROBLEM TO BE SOLVED: To provide an excellent print-traveling property with a pick strength required for pre-printing and desensitizing ink printing through a multi-sheet copying function and offset printing operation, by avoiding troubles such as paper jam, adherence to the photosensitive drum, gathering in paper feeding ans accommodation failure in the sorter even in printing as lithography paper by means of a laser beam printer. SOLUTION: Sodium salt or ammonium salt of polystylene sulfonic acid having a coating amount of 0.1-1.0g/m is added to a developer coated-layer or coupler coated-layer, thereby obtaining carbonless copying paper with a surface resistivity of 1.0×10 ohm or less.
