Abstract
A lubricant coating device preventing coating unevenness of lubricant powders is provided. The lubricant coating device includes a solid lubricant, a coating member and a film shaping member. The coating member in which first fibers composed of a material located on a positive polarity side and second fibers composed of a material located on a negative polarity side, on a triboelectric series with respect to the material of the solid lubricant are implanted, coats lubricant powders scraped off from the solid lubricant onto the image supporter. The film shaping member comes in contact with the image supporter and presses the lubricant powders onto the image supporter, to shape the lubricant powders into a form of a film. A scraping amount of the lubricant powders by the first fibers and a scraping amount of the lubricant powders by the second fibers are set to become substantially identical.
