ABSTRACT:
A developing apparatus prevents magnetic toner rise on the peripheral face of the developing sleeve to avoid scatter of magnetic toner even when a gap is caused between the developing blade and the magnetic sealing member. A magnetic plate of a base part and a protruding part, where the base has a rectangular cross-section and is in the shape of an arc extends along the peripheral face of a developing sleeve. The protruding part is on the upstream side of a doctor blade in the rotation direction in the middle of the base part in the arc length direction. The protruding part protrudes nearly perpendicularly from the side face which is perpendicular to the peripheral face of the developing sleeve, so as to cover the regions of the peripheral face of the developing sleeve from the base part to the portion facing the doctor blade.
