Abstract
A developing apparatus includes a developer bearing member, a first magnetic pole and a second magnetic pole of a same polarity as that of the first magnetic pole, and a regulating member. A regulating portion of the regulating member is provided within a range from a point of the maximum magnetic flux density of the second magnetic pole and an angular point corresponding to a half of the half value width of the second magnetic pole at the downstream side in the rotating direction of the developer bearing member.
