摘要： A fixing device includes a cylindrical fixing member, having an external circumferential surface including a crown portion curved radially outward and a inverted-crown portion curved radially inward, a pressing unit including a convexity and a concavity formed on a facing surface facing the fixing member, a first heating member to heat the fixing member, corresponding to the crown portion of the fixing member, a second heating member to heat the fixing member, corresponding to the inverted-crown portion of the fixing member, a temperature detector to detect a surface temperature of the fixing member, and a controller to control the first heating member and the second heating member independently. The pressing unit presses against the fixing member while the crown portion and the inverted-crown portion of the fixing member match the concavity and the convexity of the pressing unit, respectively, forming a curved fixing nip therebetween.
