Abstract
A doctor blade of an image forming device for controlling a thickness of a toner coated on a development roller to a uniform thickness inside the image forming device is disclosed. The doctor blade includes: a support rod serving as a support fixture; a plate formed in an L shape, the plate being mounted on the lower surface and the rear surface of the support rod in contact with them to thereby serve to keep a uniform thickness of the toner in a state where the bottom surface is in contact with the development roller, the plate including a base layer of a metallic material and a coated layer formed on the bottom surface of the base layer getting in contact with the development roller; and a torsion spring mounted above the support rod to pressurize the support rod and the plate in order to fix the support rod and the plate. The doctor blade is reusable because only the plate is simply replaced with a new one when the coated layer formed on the plate is worn out.
