Abstract:
An image forming apparatus includes a fixing unit including a heater, an air blowing portion, a first opening, a first shielding member changing an opening width of the first opening with respect to a longitudinal direction, a second opening, a second shielding member changing an opening width of the second opening with respect to the longitudinal direction, a detecting portion detecting a deviation amount of the recording material with respect to a widthwise direction, and a controller controlling, on the basis of an output of the detecting portion and size information of the recording material, the opening widths of the first and second openings so as to be different from each other by moving the first and second shielding members, respectively.

Claim (Index 16):
A fixing device for fixing toner images on recording materials in a nip by nipping and feeding the recording materials in the nip, wherein the recording materials have a first size and a second size smaller than the first size with respect to a longitudinal direction, the first size being a maximum size of the recording material on which the toner image is fixable by said fixing device, said fixing device comprising:\n an elongated heater extending in the longitudinal direction perpendicular to a feeding direction of the recording material; air blowing means configured to blow air toward one end portion and the other end portion of said heater with respect to the longitudinal direction when the recording material having the second size is inserted into said fixing device; a first opening through which air blown from said air blowing means toward said one end portion of said heater passes; a first shielding member configured to change an opening width of said first opening with respect to the longitudinal direction; a second opening through which air blown from said air blowing means toward said the other end portion of said heater passes; a second shielding member configured to change an opening width of said second opening with respect to the longitudinal direction; and detecting means configured to detect temperatures of said one and the other end portions of said heater, wherein the opening widths of said first and second openings are made different from each other by moving said first and second shielding members, respectively, on the basis of an output of said detecting means and size information of the recording material.
