Abstract
A developing apparatus includes a developer carrying member for carrying a developer to develop an electrostatic image formed on an image bearing member with a developer, and a developer feeding member, for supplying the developer to the carrying member. The developing apparatus also includes a regulating member for regulating an amount of the developer carried on the carrying member, the regulating member having a free end portion contacted to the carrying member. The developer feeding member is supplied with a voltage which is different from a potential of the developer member toward a regular charging polarity of the developer. The carrying member is provided with a surface facing substantially downward, in a range from a downstream-most edge of the developer member in the contact portion with respect to a rotational direction of the carrying member to a contact portion between the carrying member and the regulating member.
