Abstract
A pressure-sensitive cleaning sheet is disclosed which comprises a substrate, a pressure-sensitive adhesive layer formed on one or both sides of the substrate, and a porous screen disposed on the pressure-sensitive adhesive layer. The cleaning sheet is substantially non-tacky when the cleaning sheet surface is kept in a non-pressed state, and exhibits tackiness when the cleaning sheet surface is kept in a pressed state. Also disclosed are a method of using the cleaning sheet, an image-forming material having a cleaning part, and a method of cleaning an image-forming apparatus. These are useful for the cleaning of, e.g., the magnetic reading parts and magnetic-card transport parts of apparatuses accepting various magnetic cards and the thermal heads and/or transport rollers of various recording apparatuses.
