摘要： An image forming apparatus is formed by disposing a latent image-bearing member for holding an electrostatic image thereon and a toner-carrying member for carrying a magnetic toner- with a prescribed magnetic toner comprises a binder resin and magnetic powder and has a particle size distribution including 12 % by number or more of magnetic toner particles of 5 microns or smaller, 33 % by number or less of magnetic toner particles of 8 - 12.7 microns and 2 % by volume or less of magnetic toner particles of 16 microns or larger so as to provide a volume-average particle size of 4 - 10 microns. At the developing station, an alternating bias voltage comprising a DC voltage and an unsymmetrical AC voltage in superposition is applied between the toner-carrying member and the latent image-bearing member to provide an alternating bias electric field comprising a development-side voltage component and a reverse-development side voltage component. The development-side voltage component has a magnitude equal to or larger than that of the reverse development-side voltage component and a duration smaller than that of the reverse-development side voltage component, so that the magnetic toner on the toner-carrying member, particularly fine powdery fraction thereof effective for high-quality development, is effectively transferred to the latent image-bearing member to develop the electrostatic image thereon at the developing station.

摘要： A developing device includes a development roller (11), a magnetic roller (12), a transformer (83), a switching portion (81), output control portion (80) and a capacitor (82). The development roller (11) is opposite a photoconductor drum (42). The magnetic roller (12) performs, with a magnetic brush, the supply of a toner to the development roller (11) and the removal of the toner. The transformer (83) generates an alternating-current voltage applied to the development roller (11). The switching portion (81) passes and interrupts a current to the transformer (83). The output control portion (80) stepwise changes, when a duty ratio in switching is changed, the duty ratio a plurality of times from a first duty ratio to a second duty ratio. The capacitor (82) has one end connected to the transformer (83) and the other end connected to the switching portion (81).

摘要： The invention relates to a method and arrangement for inking up an applicator element (14) of an electrophotographic printer or copier. A two-component mixture, which is comprised of electrically charged toner particles and of ferromagnetic particles and which adheres to the outer surface of a roller (16), is moved past a surface of an applicator element (14) to be inked up. When the two-component mixture is moved past, at least a portion of the toner particles contained in the two-component mixture is transferred to the surface of the applicator element (14) to be inked up. An electrical field is generated that acts at least upon the portion of the two-component mixture located between the surface of the roller (16) and the surface of the applicator element (14) to be inked up. The strength of the electrical field can be controlled with the aid of a control unit so that the transferred toner particles produce a preset layer thickness on the surface to be inked up.
