Document Type and Number:
WIPO Patent Application WO/2020/183708
Kind Code:
A1
Abstract:
[Problem] To efficiently provide a powder contacting member having an intended powder adhesion suppressing effect, by forming the surface shape (surface texture) of a powder contacting member entering into contact with a powder by specifying quantitatively the surface free energy components of the powder contacting member in such a manner as to impart thereto a powder adhesion suppressing effect. [Solution] The present invention is the powder contacting member entering into contact with an organic material powder, characterized in that, in order to suppress powder adhesion, the surface shape of a powder contacting surface which enters into contact with the powder is formed in such a manner as to fulfill at least one among two conditions: (1) the hydrogen bond component, which is one of the surface free energy components for the powder contacting surface, has a value pertaining thereto which is at predetermined value or less; and (2) the polar component, which is one of the surface free energy components for the powder contacting surface, has a value pertaining thereto which is at a predetermined value or less.
