Abstract: An inkjet image forming apparatus includes a transferer and a hardware processor. The transferer transfers, onto a recording medium, ink that is ejected from an inkjet head and is borne on a transfer member. The hardware processor performs control for reducing transferability of the ink in a case where the ink borne on the transfer member is not-to-be-transferred ink, compared with a case where the ink is to-be-transferred ink.

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.

Abstract: An image forming method, includes: forming a precoat layer by applying a precoat agent onto a front surface of an intermediate transfer body; forming an ink layer by applying an ink onto a front surface of the formed precoat layer, according to an ink jet method; and transferring the formed precoat layer and ink layer to a recording medium, wherein a contact angle of the precoat agent with respect to the front surface of the intermediate transfer body is less than a contact angle of the ink with respect to the front surface of the intermediate transfer body, and a viscosity of the precoat agent is lower than a viscosity of the ink.
