摘要： A powdered toner mixture comprising a non-magnetic toner component and a ferromagnetic carrier component is caused to flow downwardly through a vertical conduit by gravity. An electromagnetic coil is wound around the conduit and energized with an alternating electric signal. An electrically conductive and magnetic mass is disposed inside the conduit. The permeability of the toner mixture decreases as the toner density, or the ratio of the toner component to the carrier component, increases. The lower the permeability of the toner mixture, the greater the proportion of magnetic flux passing through the mass. The flux passing through the mass induces eddy currents therein which, in combination with hysterisis and skin effect losses, dissipate a portion of the electric signal. The amount of power dissipation is a function of the relative proportion of flux through the mass and thereby the toner density and, when measured, provides a measure of the toner density.

摘要： An exposure unit radiates a light image of an original document onto a charged photoconductive member to form an electrostatic image through localized photoconduction. A developing unit applies a powdered developing substance comprising carrier particles and toner particles to the photoconductive member to develop the electrostatic image and produce a toner image which is transferred and fixed to a copy sheet to produce a permanent reproduction of the original document. The tone density, or the ratio of toner particles to carrier particles in the developing substance is electromagnetically measured, and the developing ability of the developing substance is opticaly measured. The developing substance is replaced when the difference between the toner density and developing ability exceeds a predetermined value. Prior to exposure with the light image a reference electrostatic image is formed on the photoconductive member and the electrostatic potential thereof is measured. The intensity of the light image of the original document and/or a developing bias voltage are regulated in accordance with the sensed electrostatic potential. The reference image may be of a reference surface having a predetermined optical density or a portion of the original document produced by reverse optical scanning.

摘要： A method of detecting the toner concentration of a two-component developer comprising a mixture of carrier particles and toner particles for use in an electrostatic copying apparatus or the like wherein a relationship between flow rate and the toner concentration of a two-component developer which passes through a container is obtained in advance, then the flow rate of the two-component developer whose toner concentration is unknown is measured by use of the container and developer flow rate detecting member. Thus, the toner concentration of the developer is determined from the measured flow rate and the relationship between the flow rate and the toner concentration which has been obtained in advance.

摘要： Deterioration of a dry developing substance causes toner particles to be so strongly adhered to carrier particles that they cannot be readily separated therefrom. The present apparatus comprises means for applying a predetermined electrostatic or air suction force to the developer to readily remove toner therefrom except for spent toner particles strongly adhered to the carrier particles. The toner density, or the ratio of toner to carrier particles, is then measured electromagnetically or optically and compared to a reference value. The developer deterioration determines what proportion of toner will be removed from the developer by said force and thereby the subsequently sensed toner density. The higher the sensed toner density, the greater the degree of deterioration.

摘要： A method for manufacturing a magnetic sensor that decreases area resistance and decreases MR ratio of the sensor by eliminating any oxide formation in the capping layer of the sensor. The method includes forming a sensor stack having a multi-layer capping structure formed there-over. The multi-layer capping structure can include first, second, third and fourth layers. The second layer is constructed of a material that is not easily oxidized and which is different from the first layer. The sensor can be formed using a mask that includes a carbon hard mask. After the sensor stack has been formed by ion milling, the hard mask can be removed by reactive ion etching. Then, a cleaning process is performed to remove the second, third and fourth layers of the capping layer structure using an end point detection method such as secondary ion mass spectrometry to detect the presence of the second layer.
