    摘要: A printer having a developer station for holding a supply of developer which includes magnetized carrier particles, a magnetized development roller, and an imaging roller proximate the development roller which collects carrier particles during operation of the printer. A scavenger proximate the imaging roller and the development roller removes the carrier particles from the imaging roller during operation of the printer which are then urged through a slot in the scavenger by the magnetized development roller.

    摘要: Developer density in an electrophotographic system is measured. The developer includes toner particles and magnetic carrier particles. First and second mutually-insulated electrodes define a working volume between them through which developer passes without contacting the first electrode. An AC voltage or current source is connected to the electrodes. An inductor is connected in series with a voltage source, or an inductor is provided in parallel with a current source. The voltage or current is applied and corresponding current or voltage across the electrodes is measured. The density of the developer in the working volume is automatically determined using a processor responsive to the measured current or voltage and the applied bias.

    摘要: A metering skive for a developer roller which is adapted to shear and/or meter developer at a developer-skive interface while minimizing compression of the metered developer. The metering skive is adjustable to various shear angles and has a geometry which enables a portion of the developer flow to be sheared away toward a curved second surface of the metering skive while metering the developer flow in a manner which minimizes or reduces compression of the developer.
