摘要： The invention relates generally to processes for electrographic image development. An electrographic development apparatus is provided wherein a film is adjacent a cylindrical toning shell and a mixture of toner and carrier is particles disposed on the cylindrical toning shell in contact with the film. The cylindrical toning shell is closest to the film at a first location, the mixture of toner and carrier particles being movable through the first location with a flow direction. A magnetic core disposed within the cylindrical toning shell offset toward the cylindrical shell such that a magnetic field strength is greater at the second location than the first location.

摘要： Apparatus and methods for electrographic image development, wherein the image development process is optimized by subjecting the developer to magnetic field maxima, thereby imparting to the developer a velocity component in a direction perpendicular to the process direction, ensuring that the toner particles thus accelerated have sufficient kinetic energy to overcome the binding energy binding the toner particles to the carrier particles in the developer, and to be deposited on a receiver bearing an electrostatic latent image. The optimized image is developed to completion, where development to completion is characterized by a proportionality between the cube of the toner charge to mass ratio and a quantity consisting of the magnitude of the voltage of the toning shell minus the magnitude of the voltage of the toned image.

摘要： An image forming apparatus of the present invention includes a developing device including a sleeve and a magnet roller fixedly accommodated in the sleeve. The magnet roller includes a main magnetic pole and an auxiliary magnetic pole adjoining it at a downstream side in the direction of rotation of the sleeve. A magnetic collection pole is positioned on the edge of an opening formed in a casing and facing a photoconductive drum. The collection pole forms a magnetic field that prevents a developer falling away from the sleeve from escaping the developing device via the opening.

摘要： A development system optimized for efficient development of an electrostatic latent image on an imaging surface. The development system includes a development material sump, a magnetic developer roll including a rotatable sleeve having located therein a rotatable magnetic core, and a developer material delivery system for providing a metered supply of developer material to the rotatable sleeve. One or more stationary magnetic shunts are located with respect to the magnetic core, sleeve, and/or developer material delivery system so as to block the magnetic field effective for attracting developer material to the sleeve, thus allowing disengagement of the developer material therefrom at a drop-off zone.

摘要： A composition for synthetic resin magnets (such as magnet rollers for electrophotography process) which is composed of a resin binder and a magnetic powder mixed and dispersed therein. The resin compound has improved melt flow rate because the binder contains a thermoplastic and an aliphatic polyamide. Owing to its improved melt flow rate, the resin compound can be incorporated with a large amount of magnetic powder without deterioration in moldability. Thus the resulting plastic magnet has a strong magnetic force. In addition, the composition for synthetic resin magnets may be incorporated with a hindered phenol antioxidant, so that it is molded at a higher temperature (120-180null C.) than usual to achieve the same object as mentioned above.

摘要： In a developing device according to the present invention, a developing roller 8 has a fixed shaft 12 and a sleeve 13. The length of a draw-up magnetic pole N3 provided in the fixed shaft 12 is made shorter than the length of a main magnetic pole N1. Accordingly, the amount of a developer adhering to both ends of an outer peripheral surface of the sleeve 13 is reduced, so that the density of the developer at both the ends of the sleeve 13 is maintained in suitable conditions in a state where the developer is over the main magnetic pole N1.
