Powder adhesion measurement methods and powder adhesion force measuring device

摘要

PROBLEM TO BE SOLVED: To provide a powder adhesiveness measuring method and a powder adhesiveness measuring device capable of properly measuring adhesiveness of a charged powder such as toner with a simple method.;SOLUTION: (1) This powder adhesiveness measuring method comprises spraying an air flow to the charged powder adhering to an adhered body, and computing the adhesiveness of the powder by use of the pressure of the air flow when the powder is separated from the adhered body. (2) The powder adhesiveness measuring device comprises a means setting the adhered body having the charged powder adhered thereto, an air flow generation means generating the air flow toward the body, a means adjusting the pressure of the air flow injected from the air flow generation means, a pressure display part, a means determining whether or not the powder is separated from the body by the air flow, and a means computing the adhesiveness of the powder from the pressure of the air flow when the powder is separated from the body.;COPYRIGHT: (C)2006,JPO&NCIPI
