ABSTRACT:
A cleaning member includes a contact portion that is in contact with a cleaning target, at least the contact portion is made of melamine resin foam that is obtained by heating and compressing an original form. Because the heated and compressed melamine resin foam is used, the wearing out of the cleaning target member is extremely less, and the cleaning capability is maintained at an adequate state for a long period of time.
