Abstract: In a developing apparatus, the developing apparatus includes a developer carrying member which carries a developer and has elasticity, and a developer regulating member which regulates an amount of the developer carried on the developer carrying member, the developer regulating member having a supported part supported by a support member and a contact part which is in contact with the developer carrying member, in which the contact part has a ten point average surface roughness of larger than 2.0 ?m and a maximum height surface roughness of smaller than an average particle diameter of the developer. Therefore, an amount of the developer carried on the developer carrying member can be regulated to be uniform.
