Abstract
A fixing device has fixation and pressure rollers in pressure contact with each other, and an application roller for applying release agent onto the fixation roller and a regulation blade for regulating an amount of the release agent so applied. The regulation blade abuts the application roller so that an extension direction of the regulation blade towards the application roller is substantially counter to a circumferential moving direction of the application roller and is provided with a chamfer at a corner between major and minor surfaces of the regulation blade at a chamfer angle of 30-70 degrees between an extension direction of the major surface and the chamfer of the regulation blade. The regulation blade abuts the application roller at an abutting angle of 30-50 degrees between the major surface and a tangent line of the application roller.
