Method of manufacturing developing roller, developing roller, and image forming apparatus |
| abstract |
An object of the present invention is to provide a method for manufacturing a low-cost and high-magnetism developing roller suitable for a slick developing device, a developing roller and an image forming apparatus. A magnet-shaped roller is formed by dispersing magnet powder in a polymer compound, and a groove-shaped housing portion is formed in a magnet roll, and a magnet corresponding to at least one developing pole is embedded in the housing portion. In this manner, as the magnet 48, a particle made of a component different from the magnet powder as an additive to the anisotropic rare earth magnet powder, and having an average particle diameter smaller than the average particle diameter of the magnet powder is added, Dispersed and formed by press molding.
