Abstract
A surface treatment method for preventing adhesion of powder to a powder-contacting member having a surface on which contacted powder flows in the form of a particle layer. The method includes performing surface treatment on the surface such that an arithmetic average peak curvature Spc (1/mm) of the surface is 150 to 400, a peak density Spd (piece/mm) of the surface is 10000 to 180000, a root mean square gradient Sdq of the surface is 0.05 to 0.30, and an arithmetic average height Sa (μm) of the surface is 0.02 to 3.00, and providing a space where an air layer can exist between the particle layer and the surface.
