摘要： In an electrostatographic process and apparatus a replenishment device adds toner particles to a development station that includes a developer comprising a mixture of toner particles and carrier particles. A reference parameter that is used in control of aim point of toner concentration in the mixture is set to an initial value until about a midlife of the developer is reached. Once the midlife of the developer is reached there are provided programmed step adjustments in the reference value in accordance with further increases in life of the developer to thereby control replenishment of toner particles so that control of charge to mass of the toner particles in the mixture is provided to reduce a tendency of dusting by the toner particles of the mixture due to age of the developer.

摘要： An electrostatographic recording apparatus and method wherein a primary charger establishes a uniform electrostatic charge on an electrophotoconductive image recording member in accordance with a first operating parameter. A recording device imagewise modulates the charge on the image recording member to form electrostatic latent images in accordance with a second operating parameter and also forms a developable process control patch. A development station develops the electrostatic latent images and the control patch on the image recording member with toner in accordance with a third operating parameter. A replenishment device provides toner to the development station at a controlled rate in accordance with a replenishment signal. A sensor senses density of the control patch developed by the development station; and a controller is responsive to density of the control patch and provides adjustments to the first, second and third operating parameters and controls a reference signal used to generate the replenishment signal as a function of a parameter related to one of the first, second or third operating parameters. Preferably the controller controls the reference signal as a function of the parameter related to the first operating parameter, primary voltage setpoint.

摘要： Particles having a controlled particle size distribution and morphology are made from inorganic hydrophilic materials by dispersing inorganic hydrophilic material in a dispersant to form a dispersion phase, and mixing the dispersion phase with a substantially water-immiscible suspending liquid, which is less polar than the dispersant, to form a suspension of dispersion phase droplets in the suspending liquid. The dispersion phase droplets are stabilized by a dispersion of an organic colloidal stabilizer which is added either to the suspending liquid before mixing or to the suspension of dispersion phase droplets after mixing. The organic stabilizer limits the coalescence of the dispersion phase droplets. The dispersant is removed to form solid inorganic particles having a controlled particle size distribution and morphology.
