Abstract

SG0134 OF THE DISCLOSURE Provided is a developing apparatus including a developer carrying member, a developer container, and a regulating member to regulate the thickness of the developer. The regulating member includes a support member such that one end is fixed to the developer container, the other end is a free end, and the support member extends in a direction opposite to the rotating direction of the developer carrying member, and a contact member to be fixed to the other end of the support member and to contact the developer carrying member. The contact member includes a contact curved surface along a peripheral surface of the developer carrying member, and an opposite surface to face the developer carrying member. The contact pressure of the contact curved surface applied to the developer carrying member decreases as a location on the developer carrying member approaches downstream side in the rotating direction.
