Abstract:
A toner cleaning sheet includes at least one type of fiber selected from among different thermoplastic fibers formed of thermoplastic resin with a melting point of 265° C. or more and at least one type of fiber selected from among different cellulose fibers, wherein at least part of the aforementioned thermoplastic fiber is fusion-bonded to neighboring thermoplastic fiber filaments. The toner cleaning sheet can be produced by a method that includes at least one type of fiber selected from among different thermoplastic fibers formed of thermoplastic resin with a melting point of 265° C. or more and at least one type of fiber selected from among different cellulose fibers, the method including a bonding step in which at least part of the aforementioned thermoplastic fiber is fusion-bonded to neighboring thermoplastic fiber filaments.
