Abstract: An invented pressure-sensitive adhesive sheet for removal of a solvent-containing substance includes a substrate and a pressure sensitive adhesive layer formed at least on one side of the substrate, and the pressure sensitive adhesive layer adsorbs 20 g/m2 or more of a solvent contained in the substance to be removed when the sheet is immersed in the solvent for 3 minutes. Another invented pressure-sensitive adhesive sheet for removal of a solvent-containing substance includes a substrate and a pressure sensitive adhesive layer formed at least on one side of the substrate, the pressure-sensitive adhesive layer absorbs 5 g/m2 or more of a solvent contained in the substance to be removed when the sheet is immersed in the solvent for 1 second, and the sheet after absorbing 5 g/m2 of the solvent has a tackiness of 1 cN/25-mm or more as determined by a method in conformity with JIS Z 0237.

Abstract: The present invention provides a dust remover having a dust removal roller for removing the dust attached on the surface of a dust removal object by coming in contact with the surface of the dust removal object while rotating, and an adhesive tape roller for transferring the dust adherent to an outer peripheral face of the dust removal roller to an adhesive layer of the adhesive tape roller to clean the dust removal roller, while rotating with its outer peripheral face in contact with the outer peripheral face of the dust removal roller. An outer peripheral layer of the dust removal roller is made of a non-silicone elastic body, and a difference &Dgr;&dgr; between a solubility parameter (SP value) &dgr;A of the non-silicone elastic body and a solubility parameter (SP value) &dgr;B of an adhesive applied on the adhesive layer of the adhesive tape roller is 1.0 [J/cm3]½ or greater.
