CLEANING SYSTEM

摘要

Foreign materials can be continuously attracted by means of a cleaning roller for a relatively long period of time without requiring maintenance. A cleaning roller (11) is brought into contact with the surface (S1) of a material to be cleaned (S), and the foreign materials, such as dusts, which are adhered on the surface (S1) of the material to be cleaned (S) are removed using an electrostatic force. A transfer roller (51) is provided on the cleaning roller (11) surface on the reverse side of the surface having the material to be cleaned (S) thereon, and the foreign materials adhered on the cleaning roller (11) are transferred onto the transfer roller (51). An electrostatic charge control roller (21) which rotates in contact with the outer circumferential surface of the cleaning roller (11) is provided, and the electrostatic charge quantity of an outer layer section (11c) of the cleaning roller (11) can be controlled. As a material for forming the outer layer section of the transfer roller (51), a material which can be charged with electrostatic charges that can attract the foreign materials adhered on the outer circumferential surface of the cleaning roller (11) to the outer circumferential surface by means of an electrostatic force is selected.
