摘要： In an image forming apparatus, a magnet brush forming device includes at least a first magnetic pole facing an image carrier carrying a latent image and a second magnetic pole positioned downstream of the first magnetic pole in the direction of rotation of a developer carrier. When a magnet brush formed on a developer carrier by the first magnetic pole forms a nip between it and the image carrier, flux density in the direction normal to the developer carrier has an attenuation ratio of 40% or above. The second magnetic pole has an upstream half-value point located downstream of a point upstream of and angularly spaced from the edge of a developer storing member by 15null. Flux density in the normal direction and flux density in the tangential direction between the first and second magnetic poles have vectors the sum of which is 85 mT or above.

摘要： In a two-component developing unit, by devising the layout of magnetic poles 6 (particularly a pickup magnetic pole 6b and a trimming magnetic pole 6c) of a magnet member 5 arranged inside a developer carrier 3, an excess portion of a developer G picked up onto the surface of the developer carrier 3 is allowed to drop in the vicinity of the height of the rotational center O of the developer carrier 3, and only the developer G restricted to a predetermined layer thickness is carried and transported to a development region m. A charging member 9 is disposed over a periphery of the developer carrier 3, as required. In addition, the layout of the magnetic poles 6 of the magnet member 5 arranged inside the developer carrier 3 is set variably between the time of development and the time of nondevelopment, and the amount of developer carried on the surface of the developer carrier and transported to the development region m is set to substantially zero at the time of nondevelopment.

摘要： A developing apparatus comprises a hollow cylindrical sleeve which is rotationally driven and a magnetic shaft which is rotationally driven inside the sleeve. The magnetic shaft causes the magnetic toner to adhere to the peripheral surface of the sleeve by the magnetic force. The magnetic toner adhering to the peripheral surface is supplied to the developing position by rotation of the sleeve and adheres to the electrostatic latent image formed on the surface of a photosensitive body. The center of rotation of the magnetic shaft is deviated from the center of rotation of the sleeve nearer to the photosensitive drum, and frontward along the direction of rotation of the sleeve from a line connecting the center of rotation of the sleeve and the center of rotation of the photosensitive body.

摘要： An apparatus and a method for manufacturing a magnet roller makes it possible to remarkably reduce defects on the surface or the inside of a magnet roller and also to control nullwarpnull of the magnet roller sufficiently so that it does not adversely affect the functions of the magnet roller. A metal mold for magnetic field injection molding is composed of two fixed mold counterparts and a movable mold counterpart. The movable mold counterpart is moved to increase the volume of the cavity of the metal mold as a resin-bonded magnet material is injected into the mold.
