摘要： An image forming apparatus operates in such a way that when the conditions of toner (9) changes due to changes in environmental conditions, changes with age, and replacement of an EP cartridge (13), the bias voltages for a charging roller, a developing roller (2), and a toner-supplying roller (3) are set appropriately. An electrostatic latent image can be formed on a photoconductive body (1). The developing roller (2) causes developer to adhere to the electrostatic latent image to develop the electrostatic latent image. The toner-supplying roller (2) supplies the developer to the developing roller (2). The current measuring section (28) measures a current flowing through at least one of the developing roller (2) and the toner-supplying roller (3). An voltage-setting section (27) sets at least one of the developing roller (2) and the toner-supplying roller (3) to a corresponding one of first voltages, the first voltages being set in timed relation with development of the electrostatic latent image.

摘要： In a case where there are developers belonging to Life Rank 1 representing a service life substantially as long as that of a fresh developer (Step S501), and the developers includes one which is ready to print (Step S502), it is determined that image formation can be performed without performing a preparatory operation (Step S506). In a case where there is no print-ready developer but a developer which requires an agitation operation of rotating a developing roller by a predetermined quantity (Step S503), the agitation operation is performed on the developer (Step S504) so as to make the developer in a print-ready state. In a case where the developer cannot be made print-ready by the agitation operation, a density control operation for adjusting operating conditions of an apparatus is performed (Step S505). Thus is obviated an unnecessary operation. The developer subjected to a predetermined print preparatory process is used in a printing operation so that an image of good quality may be formed. In a case where no Rank-1 developer is available but a Rank-2 developer, deteriorated to a degree, is available, the same procedure is taken.

摘要： In a method for controlling a development process in an electrographic printer or copier, a mixture of toner and carrier particles is used. For the state of the mixture, a characteristic value D or E is determined from model calculations, an operating ageing rate or a time constant being taken into account. The development process is subjected to open-loop or closed-loop control depending on the characteristic values D and/or E.
