摘要： A developing apparatus for developing a latent image includes a container, a developer carrying member movable along an endless path from inside the container to the outside, a magnetic field generator inside the carrying member, a partition member in the container for separately supporting, before operation, a first developer of magnetic particles and a second developer of non-magnetic particles, and a regulating member cooperable with the magnetic field generator. Upon release of the partition member, the first developer forms a base layer on the carrying member and the second developer forms on the base layer and then, upon circulation of the carrying member the second developer is moved past the regulating member.

摘要： In a magnet roll comprising a plurality of magnet pieces adhesively secured to a supporting shaft, to increase the magnetic flux density of a particular magnetic pole, the magnet pieces are disposed so that they have repelling magnetic forces in the interface between the magnetic piece having said particular magnetic pole and the magnet piece adjacent thereto. Further, in a unitarily molded magnet roll comprising a unitarily molded magnet secured to a supporting shaft, the cross-sectional shape of the shaft is selected in accordance with magnetized poles, whereby the positions of the magnetic poles are prescribed relative to the shaft and a strong magnetic force is obtained.
