Abstract

The developing device includes a casing, a developing roller, a thickness regulating blade, and a seal member. The developing roller has an outer peripheral surface carrying developer. The thickness regulating blade is configured to regulate a thickness of the developer carried on the outer peripheral surface and has an opposed surface confronting the casing. The thickness regulating blade further has one end part supported on the casing and another end part provided with a press member in sliding contact with the outer peripheral surface. The press member is located on the opposed surface and protrudes toward the developing roller. The press member is formed with a receiving portion depressed inward at its widthwise ends in an axial direction of the developing roller. The seal member is disposed between the thickness regulating blade and the casing and contacting at least a part of the receiving portion.
