Abstract
A heat roller type fixing apparatus which prevents forming of wrinkles on a material for printing and eliminates a jitter of a picture. The apparatus comprises a single fixing roller equipped with a heater, and two pressing rollers pressed to the fixing roller. The fixing roller and the two pressing rollers are arranged so that a collision angle, an angle in which the printing material ejected from a nip portion of a first pressing roller collides with a second pressing roller, is less than 67 degrees.
