Abstract

PROBLEM TO BE SOLVED: To unnecessitate operation space and to surely remove dust by forming a self-adhesive surface on the surface of a base material sheet. SOLUTION: This roller cleaner A is constituted by forming a self-adhesive surface A2 on the surface of the base material sheet A1. The sheet A1 is formed out of a synthetic resin material, which is excellent in mechanical property such as tensile strength and has such a property that curling is not imparted even when the material passes through the bent part of a paper carrying path. The self-adhesive surface A2 of the roller cleaner A is formed by coating the surface of the sheet A1 with a pressure sensitive adhesive. The adhesive having weak adhesive strength is adopted as the pressure sensitive adhesive. To put it concretely, the pressure sensitive adhesive is prevented from being stuck to a carrying roller and the sheet A1 of the roller cleaner A is prevented from being wound round the carrying roller at the time when the roller cleaner A passes the carrying roller, and has the adhesive strength to such an extent that the dust such as the paper powder, etc., stuck to the carrying roller can be removed.
