Claims

[Scope of utility model registration request]

In a developing roller for adhering magnetic toner to a photoreceptor by frictional charging, the surface of which is made of fibrous flocking, the fibrous flocking is a fibrous material having a high magnetic permeability magnetic material on its surface. It consists of something attached,
In the case of a fibrous material, it is characterized by being a mixture of two types of flocking, one made of a highly permeable material and one made of a non-magnetic material, or the tip of a fibrous flocked material is coated with a high permeability magnetic material. developing roller.
