CLEANING SYSTEM

摘要

Provided is a system in which the adsorption of foreign matter by a cleaning roller can be continued for a prolonged period of time without performing maintenance operations on the cleaning roller. The disclosed cleaning roller (11) moves relatively with respect to an object to be cleaned (S) while rotating and contacting the surface of the object to be cleaned (S), and removes foreign matter, such as dust and dirt, adhering to the surface of the object to be cleaned (S) by utilizing electrostatic force. A transferring roller (21) rotates while contacting the surface of the cleaning roller (11). The cleaning roller (11) is grounded via a voltage stabilizing circuit (12), and can have the roller surface charged stably with an electric charge for carrying out adsorption with said electrostatic force. The transferring roller (21) can have the surface thereof charged with an electric charge for adsorbing foreign matter adhering to the surface of the cleaning roller (11) by utilizing electrostatic force, and the transferring roller is connected to an external power source (31) such that the electrification voltage for the adsorption of said foreign matter with said electrostatic force is kept constant.
