Abstract:
1. A developing device that is attachable to a main body, the developing device comprising: a chassis having an opening; a developer carrying member that carries a developer on a surface thereof; a thickness regulating member that pressure-contacts a surface of the developer carrying member and that regulates a thickness of the developer carried on the surface of the developer carrying member; a supply member that contacts the developer carrying member and that supplies the developer to the developer carrying member; and a conveying member that conveys the developer so that the developer is supplied to the supply member, wherein the developer carrying member, the thickness regulating member, the supply member, and the conveying member are provided within the chassis, and wherein in a state in which the developing device is attached to the main body: the opening of the chassis faces upward; an upper portion of the developer carrying member is exposed from the opening; the thickness regulating member pressure-contacts the surface of the developer carrying member from below the developer carrying member; the conveying member is disposed below the developer carrying member and conveys the developer in a longitudinal direction of the conveying member; the supply member overlaps with at least a portion of the conveying member in a horizontal direction; and at least a portion of the conveying member is disposed within a vertical projection plane between a pressure-contact position of the thickness regulating member to the developer carrying member, and a contact position of the supply member to the developer carrying member.
