Abstract
A developing device includes: a developing container for accommodating developer, a developer carrying member, and a plate-like elastic member. In a state in which the elastic member contacts the developer carrying member without being deformed, an angle formed between a flat reference surface passing through a surface of the elastic member which is continuous to a contact portion of the elastic member with the developer carrying member and which is downstream of the contact portion with respect to the movement direction and a tangent plane of the developer carrying member and a contact position between the elastic member and the developer carrying member is 10° or more and 45° or less, and the elastic member includes a first region including the contact portion and a second region which is provided continuously from the first region toward the supporting portion and which is lower in rigidity than the first region.
