ABSTRACT:
A fixing device comprises a thermally fixing roller, a belt, and pushing means which pushes the belt toward the thermally fixing roller. A nipping region is formed between the belt and the thermally fixing roller. A maximum pressure is produced in an upstream end region of the thermally fixing roller in the direction of rotation in the nipping region, another maximum pressure is produced in a downstream end region thereof in the direction of rotation in the nipping region, and a pressure is produced in an intermediate region, which pressure being not higher than the maximum pressure in the upstream end region and not higher than the another maximum pressure in the downstream end region.
