ABSTRACT:
An electrostatic latent image developing apparatus has a developing sleeve drivingly rotatable for supplying a magnetic developer to an image bearing surface of an electrostatic latent image bearing member, a casing covering at least a portion of the developing sleeve and extending from a portion where the sleeve is opposed to the electrostatic latent image bearing member to a position where the developer is supplied to the sleeve with respect to the direction of rotation of the developing sleeve, the casing defining a gap with the sleeve, magnets fixedly positioned in the sleeve and having a plurality of poles opposed to the casing, the plurality of poles including first and second poles of same polarity and a third pole of different polarity, the first and second poles being positioned adjacently with no pole therebetween, whereby a first bristle of developer for sealing the gap is formed by the first and second poles and a second bristle of developer for sealing the gap is formed by the third pole.
