发明名称 IMAGE FORMING DEVICE, IMAGE FORMING METHOD AND DEVELOPING APPARATUS
摘要 <p>PROBLEM TO BE SOLVED: To provide an image forming device, an image forming method and a developing apparatus capable of realizing miniaturization and the prolongation of the life of two-component developer and restraining density irregularity of a screw pitch state. SOLUTION: In this image forming device using the two-component developer, a stirring and carrying means has: a developer layer thickness regulating pole; and a peeling pole having the same magnetic polarity as the regulating pole, arranged adjacently to the regulating pole and on the upper side in the gravity direction of the regulating pole and forming magnetic field for peeling the two-component developer served for development from a non-magnetic cylinder. The stirring and carrying means is constituted so that the peak value of the intensity of the magnetic field of the regulating pole in the normal direction of the non-magnetic cylinder is larger than that of the peeling pole in the normal direction thereof as an absolute value by >=0 tesla and <=0.02 tesla, and stirs and carries the developer in a developing container. The uppermost level of the developer carried by the stirring and carrying means is positioned between the peak position of the intensity of the magnetic field of the regulating pole in the normal direction of the non-magnetic cylinder and that of the peeling pole in the normal direction.</p>
