PROBLEM TO BE SOLVED: To provide a magnetic sealing member having excellent magnetic sealing performance and realizing the reduction of cost and light weight. SOLUTION: This magnetic sealing member 1 is disposed between the outer peripheral surface of both ends of the developing sleeve for feeding toner by rotating while carrying the toner stored in a toner storage part on its surface and supplying it to the surface of a latent image holding body and the toner storage part, and provided with a circular-arc shaped sealing part 11 preventing the toner carried on the surface of the developing sleeve or the toner in the storage part from being scattered from both ends of the developing sleeve. It is composed of resin magnetic composition where anisotropic magnetic powder is dispersed in resin binder, and at least the sealing part 11 is a magnetic sealing part magnetized by orienting the magnetic powder in a specified direction. |
