Abstract: A contacting member contacts a region of a contacted member to which a liquid composition has been applied. The contacting member has a substrate and a fluororesin fiber layer containing a fluororesin fiber. One side of the fluororesin fiber layer is directly or indirectly fixed to the substrate and another side of the fluororesin fiber layer contacts the contacted member. A ratio X/Y is less than 1.00, wherein X is a presence ratio of the fluororesin fiber in the fluororesin fiber layer on the side which is directly or indirectly fixed to the substrate and Y is a presence ratio of the fluororesin fiber in the fluororesin fiber layer on the other side which contacts the contacted member.

Abstract: A contacting member is provided that contacts a region of a contacted member to which a liquid composition has been applied. The contacting member has a fluororesin fiber layer containing a fluororesin fiber, which is disposed on a surface which contacts the contacted member. The fluororesin fiber layer has an average deformation amount of from 5.0 to 18.0 ?m/N, which is calculated from a displacement amount obtained when a circular indenter having a diameter of 5 mm is pushed into the fluororesin fiber layer.
