Abstract:
1. A heater, comprising a first heating member and a second heating member pressing each other, said first heating member comprising internal heat sources; said second heating member without an internal heat source; wherein said heater heats a heated material by passing the heated material through a press region where the first heating member and the second heating member meet, said heater further comprising an external heating member heating the second heating member so that the second heating member has a predetermined surface temperature, wherein the first heating member and the second heating member each have a center of rotation positioned horizontally with respect to each other and the heated material passes through the press region between the first heating member and the second heating member vertically either in an upward or downward direction, wherein the second heating member has a center of rotation and a first surface region positioned below the center of rotation and a second surface region positioned above the center of rotation, the first surface region extending between The external heating member and the press region in the direction of rotation of the second heating member, the second surface region extending between the external heating member and the press region in the direction counter to the rotation of The second heating member, the first surface region being smaller than the second surface region and the external heating member contacting the second heating member at a position on a first side of the second heating member, with respect to a vertical line through the center of rotation, opposite to a second side of the second heating member, with respect to the vertical line through the center of rotation, where the press region is located.
