の使用は困難であった。[0003] The use of recovered powder (a powder coating that has been applied once but dropped without being applied and collected by a cyclone or a bag filter), which is one of the major characteristics of the powder coating, is a powder coating that serves as a base. When the powder for coloring and the powder for coloring are mixed by the dry blending method, when the electrostatic coating is performed, the difference between the electric resistance of the powder for powder coating and the powder for coloring as a base causes the coating to be performed on the object to be coated. Efficiency is different, and as for the recovered powder, the finished feeling after painting is often greatly different from that of the so-called Shinbata in the purchased state, and it is difficult to use the same powder on the same substrate.
