Abstract
In a method for evaluating a fixing member to fix a toner having a surface layer, a hardness test is carried out by applying a pressure deformation from the surface side of the fixing member, and when a deformation of the surface layer by the pressure deformation is within an elastic range, the fixing member is regarded as a standard product.
