Characteristics of Development
Abstract:Two-component development systems using magnetic carriers and tribocharged toner particles are well established in electrophotography for high-quality development of electrostatic latent images at high speed. Two main approaches are used for these systems: development utilizing fixed magnets within a rotating developer roller, or development with a moving magnetic field, usually produced by a developer roller with a rotating magnetic core as well as a rotating outer surface or shell. The magnetic field from the rotating magnetic core provides a large amount of kinetic energy to the carrier and the toner particles moving toward the electrostatic latent image. Development to completion has been obtained with a rotating magnetic core development system. Completion is characterized by proportionality between the cube of the toner-charge-to-mass ratio, Q/m, and the voltage to completion, Vc, which is the difference between the developer bias and the voltage of the developed image.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
