Patent ID: 7747205

Claim:
An image forming apparatus comprising: a fixing device including a heating member which heats a recording material, a pressing member which comes into contact with the heating member with pressure, and an air separator which separates the recording material from the heating member by compressed air blown between a leading edge of the recording material and the heating member; and a conveyance member which conveys the recording material with reference to a center of the recording material in a width direction perpendicular to a conveyance direction of the recording material, wherein the air separator includes a plurality of nozzles disposed in the width direction and an air emitting amount distribution setting section which controls an emitting amount distribution in the width direction of the compressed air which is emitted from the nozzles so that a center portion of the air emitting amount distribution in the width direction becomes high; and wherein the air emitting amount distribution setting section sets the air emitting amount distribution by arranging each of the nozzles having a nozzle diameter different from each other.
