摘要： An electrographic development apparatus comprises a magnetic brush applicator having cooling means for dissipating thermal energy from the developer as it is transported by the brush. Such cooling means preferably comprises means for passing a cooling fluid through the interior of the brush while in use. Alternatively, such cooling means comprises a hollow skive through which a cooling fluid is circulated.

摘要： A replaceable development station usable for developing electrostatic images in an apparatus having a toner monitor and a channel for slidably receiving the development station includes a chamber containing a supply of a development mixture of toner and carrier particles. A recess is defined in one wall of the chamber for receiving the toner monitor, the recess being defined by a thinned region of the wall such that the toner monitor is separated from the developer mixture by a wall region substantially thinner than the general wall thickness.

摘要： A device for developing electrostatic images includes a toner supply chamber for holding a supply of dry toner and a feed member located generally at the bottom of the supply chamber. To break up agglomeration of toner in the supply chamber an agitator, for example an elongated polypropylene fiber brush, is placed on top of the feed member and is supported totally at its periphery by the feed member and associated walls of the supply chamber. As the feed member rotates, the agitator is rotated to maintain the toner in particulate form.

摘要： Electrographic development is obtained by predeterminedly rotating an alternating pole core of a magnetic brush applicator, within a surrounding applicator shell, to supply developer, of the kind including small particle, hard-magnetic carrier and electrically insulative toner, to an electrostatic imaging member which moves past a development station with predetermined linear velocity. The shell can be stationary or rotate at a velocity significantly less than the image member velocity. The core is predeterminedly rotated so that (i) its fields effect a large portion of transport through the development zone and (ii) the developer moves co-currently with the imaging member and at a linear velocity generally equal to the imaging member velocity.

摘要： In a novel electrographic copying method and apparatus, a latent electrostatic image is formed on an insulating layer of an electrophotographic element and, before, during or after the formation of the latent electrostatic image, there is created a plurality of charge islands, such as by an exposure through a screen. These charge islands are distinct and in addition to any charge islands which result from the image-forming step. After establishment of the charge islands and the latent electrostatic image, the resulting charge pattern is developed with a developer which either is at least partially conductive, i.e., has a maximum resistance of about 10.sup.9 ohms, or is rendered so by the phenomenon of electrical breakdown.

摘要： Improved electrographic development apparatus and procedure for use with partially-conductive developer employs transport of the developer through a first development zone in a direction generally countercurrent to a moving image member and through a second development zone in a direction generally co-current to the moving image member. The extent of image development within each such zone is controlled by the rate of developer transport and/or the magnitude of developer bias, so that overall development of the different portions of large solid image areas (particularly leading and trailing portions of such areas) is equalized.

摘要： A toner monitor in an electrostatographic machine is automatically calibrated when a toner monitor is periodically caused to read a simulated nominal toner concentration. Any difference between the monitor's output and that expected for the simulated nominal toner concentration is applied to a compensation device. The simulated nominal toner concentration signal is obtained by periodic alignment of the toner monitor with a magnetically permeability member.

摘要： A development station for developing electrostatic images includes a housing which has a vertically oriented separating wall which divides the housing into first and second chambers. In assembly both chambers are open at the top permitting ready loading of one chamber with a mixture of toner and carrier and the other chamber with substantially toner. The separating wall includes an opening at the bottom for passage of toner into the chamber containing the mixture. A toner applicator is located at the top of the chamber containing the mixture and a cover is permanently affixed across the tops of the chambers, totally sealing the chambers except for an opening in the cover opposite the toner-applicator. Because of the design of the station, especially the chambers which are open at the top for easy loading of toner and carrier, the station can economically be made disposable. A method for assembling the elements which make up the development station and for loading the toner and/or carrier in the various chambers is also described.
