Abstract:
A change of a magnetic flux density distribution adjacent to a regulating blade  9  opposed to a developer regulation pole is suppressed at a low cost, while suppressing influence to design latitude of magnetic poles. A position on the outer peripheral surface of the developing sleeve where the magnetic flux density in the normal line direction of the outer peripheral surface of the developing sleeve is a maximum value position. The position on the outer peripheral surface of the developing sleeve  8  corresponding to a center portion position of the half peak range of the magnetic flux density distribution of the developer regulation pole is called half peak center portion. The developer regulation pole is formed such that the maximum value position is deviated not less than 3° in the circumferential direction of the developing sleeve from the half peak center portion position, and the position when the regulating blade  9  opposite is the developing sleeve is in a side of the maximum value position in which the half peak center portion position exists.

Claim (Index 1):
A developing apparatus comprising:\n a developing container configured to accommodate a developer containing toner and carrier; a developing sleeve rotatably supported by the developing container and configured to carry the developer from said developing container; and a magnet provided in said developing sleeve and having a plurality of magnetic poles arranged in a circumferential direction; and a regulating member provided opposed to said developing sleeve with a predetermined gap therebetween and configured to regulate a layer thickness of the developer carried on said developing sleeve, wherein said magnetic poles include a regulation pole disposed opposed to said regulating member, and said regulation pole is disposed such that a maximum value position at which a magnetic flux density in a normal line direction of said developing sleeve is a maximum is not less than 3\u00b0 away in a circumferential direction of said developing sleeve from a half peak center portion position which is a center portion position of a half-peak width of the magnetic flux density, and wherein said regulating member is disposed in a side of the maximum value position including the center portion position with respect to the circumferential direction of said developing sleeve.
