Supply device, developing device, and image forming apparatus

A developing device comprising:

• a developing member that develops an electrostatic latent image on an image holding member by using a liquid developer while rotating;
• a supply device for a liquid developer that supplies the liquid developer to an outer peripheral surface of the developing member;
• and
• a control section,
• wherein the supply device for the liquid developer includes a plurality of supply members, and each of the supply member has a cylindrical shape with recesses regularly disposed on an outer peripheral surface, faces the developing member developing while rotating, draws up the liquid developer accommodated in an accommodation section while rotating, supplies the liquid developer to the outer peripheral surface of the developing member, and is arranged along a rotation direction of the developing member, and
• wherein when the developing member develops, the control section controls a rotation starting time for the plurality of supply members so that a position of a peak of a thickness of the liquid developer supplied to the outer peripheral surface of the developing member by a first supply member is different from a position of a peak of a thickness of the liquid developer supplied to the outer peripheral surface of the developing member by a second supply member.
