Zusammenfassung: | PROBLEM TO BE SOLVED: To produce a manuscript paper, the indication part such as rules or the like applied on which vanishes or turns into a state nearly equal to vanish under the condition being copied by an optical copying apparatus, by a multikind and small quantity production method. SOLUTION: This manuscript paper is equipped with a visible indication part formed through the fixture of black toner particles. In this case, the displaying part consists of a plurality of the black toner particle groups, which have a predetermined degree of concentrations and are arranged at the predetermined intervals on the plain part of a paper. In addition, the above-mentioned degree of concentrations and intervals are set so as not to reproduce the indication part by an optical copying apparatus. |
