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.
