Abstract
When a developing device is seen in a cross section orthogonal to a rotation axis of a rotatable developing member, a resin-made regulating blade has a cutout over an entirety of a region from a first position where the regulating blade is closest to the rotatable developing member to a second position 0.5 mm downstream of the regulating blade from the first position in a rotation direction of the rotatable developing member, and a cut amount of the cutout at the second position is 0.3 mm or more.
