发明名称 VERFAHREN ZUM STEUERN DES BILDSCHWAERZUNGSGRADES BEI EINEM ELEKTROPHOTOGRAPHISCHEN VERFAHREN
摘要 A recording image density control method for electrophotography comprising the steps of forming at least two latent electrostatic image patterns with different electric potentials on the surface of a photoconductor; developing the latent electrostatic images patterns to toner image patterns by use of toner contained in the developer; detecting data relevant to image density for each developed toner image pattern (such as the image density of each developed toner image pattern, for instance, by a toner image pattern, for instance, by a photosensor), with a different resolution for each image pattern; determining the ratio of the data for one image pattern to the data for the other image pattern by A/D conversion; and controlling at least one recording image density controlling parameter, such as the amount of the toner supplied to a development apparatus, in accordance with the ratio for controlling recording image density, whereby recording image density can be controlled.
