Claims

[Scope of utility model registration request]

In a developing device that develops a latent image carrier by transporting magnetic toner on the surface of a developing sleeve while rotating a magnet provided inside, a porous or open-cell sponge such as an open-cell sponge that contacts the developing sleeve is used. A developing device configured to regulate the supply amount of the magnetic toner using a brush-like member.
