Fusing apparatus and method

摘要

A fusing apparatus including a heating unit (100) including a heater (110) having a substantially flat shape; a nip forming unit (200) which faces the heating unit and forms a fusing nip with the heating unit; and a driving unit (400) which moves the heating unit to alternately repeat a forward motion whereby the heating unit moves forward in a moving direction of the recording medium, when the fusing nip is formed, and a returning motion whereby the heating unit moves backward in a direction opposite to the moving direction of the recording medium, when the fusing nip is released.
