摘要：
A fixing device that fixes an unfixed toner image onto a moving sheet, includes a first fixing unit that makes toner of the unfixed toner image penetrate into the sheet by heat and pressure so as to be fixed onto the sheet as a fixed toner image, and a second fixing unit arranged downstream of the first fixing unit in a sheet moving direction to contact and press the fixed toner image on the sheet to change smoothness of a surface of the toner of the fixed toner image on the sheet. The second fixing unit is arranged at a position where a temperature of the toner of the fixed toner image on the sheet is greater than a glass transition temperature.
