Abstract:
A cleaning apparatus including: a normally-charged toner cleaning member that receives a voltage having a polarity reverse to a normal charging polarity of a toner and electostatically removes a toner having the normal charging polarity on a cleaning target; a reversely-charged toner cleaning member that receives a voltage having the same polarity as the normal charging polarity of a toner and electrostatically removes a toner having a polarity reverse to the normal charging polarity on the cleaning target; and a pre-cleaning member that is disposed at an upstream side of the normally-charged toner cleaning member and the reverse-charged toner cleaning member in a surface moving direction of the cleaning target, receives a voltage having a polarity reverse to the normal charging polarity of the toner, and electrostatically removes a toner having the normal charging polarity on the cleaning target, is provided.
