Abstract: METHOD FOR DEVELOPMENT OF A LATENT ELECTROSTATIC IMAGE EMPLOYING A DONOR MEMBER ADAPTED TO RETAIN TONER ON ITS SURFACE AND HAVING A NUMBER OF PROCESSING STATIONS ARRANGED AROUND ITS PERIPHERY THE DONOR MEMBER HAS A CORONA-CHARGEABLE DIELECTRIC SURFACE AND IS POSITIONED SO THAT A PORTION OF ITS PERIPHERY PASSES THROUGH TONER IN A VIBRATING RESERVOIR. THE RESERVOIR IS MAINTAINED AT A POTENTIAL LOWER THAN THE CHARGED DONOR MEMBER. THE TONER IS TRIBOELECTRICALLY CHARGED IN THE VIBRATING RESERVOIR VIA A COATING ON THE INSIDE OF THE RESERVOIR CAPABLE OF SO CHARGING THE TONER AND SAID TONER IS ATTRACTED TO THE DIELECTRIC SURFACE OF THE DONOR WHICH IS CORONA CHARGED OPPOSITELY TO THAT OF THE TONER.

Abstract: A toner concentration sensing apparatus arranged in the circulation path of developing material in an electrostatic reproduction machine and having a housing into which some of the moving developing material is diverted. The apparatus includes means in the housing or splitting the inflowing material into a plurality of paths each of which has associated therewith a toner concentration sensing device all of which cooperate with a toner replenishing means. A timing mechanism is connected to the sensing devices for periodically controlling their operation as toner concentration sensing devices.

Abstract: An electrostatic copying device including a donor roller for supplying a layer of toner and a photoreceptor drum and associated components for generating a latent image are operated in consort in a two-rotation cycle of operation under controlled condition. During the first rotation of the cycle of operation the photoreceptor is uniformly charged with a relatively low corona charge and the photoreceptor is used as a biased roller to make uniform the layer of toner placed on the donor roller. During the second rotation of the cycle of operation the latent image is generated and the latent image is developed using the uniformly made toner layer.

Abstract: XEROGRAPHIC APPARATUS FOR THE MAGNETIC BRUSH DEVELOPMENT OF LATENT ELECTROSTATIC IMAGES WITH A TWO-COMPONENT MAGNETIC DEVELOPER. THE APPARATUS INCLUDES A PLURALITY OF ROLLERS WITH MAGNETIC FIELDS EXTENDING THEREFROM POSITIONED ADJACENT A LATENT ELECTROSTATIC IMAGE BEARING SURFACE TO BE DEVELOPED WITH THEIR AXES OF ROTATION PARALLEL TO EACH OTHER. DRIVE MEANS ARE PROVIDED TO ROTATE EACH ROLLER IN A DIRECTION OPPOSITE TO EACH ADJACENT ROLLER. IN THIS MANNER, ALTERNATE ROLLERS FUNCTION AS MAGNETIC BRUSH DEVELOPING ROLLERS WHILE THE INTERMEDIATE ROLLERS FUNCTION AS DEVELOPER TRANSPORT ROLLERS TO MAGNETICALLY TRANSPORT THE DEVELOPER FROM ONE DEVELOPING ROLLER TO THE NEXT. WHEN A SUMP OF DEVELOPER IS PROVIDED ADJACENT THE LOWERMOST ROLLER, GRAVITY MAY BE UTILIZED TO RETURN DEVELOPER FROM THE UPPERMOST ROLLER TO THE SUMP. BAFFLES MAY ALSO BE EMPLOYED TO CROSS-MIX DEVELOPER RETURNING TO THE SUMP.

Abstract: To control toner used in developing a latent electrostatic image carried by, say, a photoconductive surface, there is a shaped electric field acting on a toner laden donor member for separating toner from the donor member as it enters a development zone and for redepositing any excess toner on the donor member as it leaves the development zone.

Abstract: A transfer roller assembly having a transfer roller, is mounted adjacent a curved photoconductive surface of an electrostatographic machine so that the transfer roller is biased into contact with the surface with a minimal force sufficient only to maintain uniform contact therewith during machine operation; the roller is mounted so that it may move in a direction which is at least generally perpendicular to a tangent at the point of contact. The ratio of the radius of the photoconductive surface to that of the roller at the point of contact is not less than 3, and preferably in the range of 3 to 3.5.

Abstract: In an electrostatic recording system in which a donor roller is employed to carry a layer of toner to the photo-receptor member for use in developing an electrostatic latent image, the donor roller is loaded with a uniform layer of toner by rotating the donor roller through a bath of toner in a vibrating pan. The donor roller is positioned so that a portion of its circumference passes through the toner in the vibrating pan forming a varying depth bath of toner, the thinnest depth of toner being sufficiently thin to fluidize the toner in this thin layer area. In this thin level of toner the vibrations of the vibrating pan drives the toner into a highly fluid state and the toner adheres to the surface of the donor roller thereby loading the roller with a layer of toner. The layer is wiped to a uniform thickness as the roller passes through thicker levels of toner in the toner bath which are not in a fluid state.
