Abstract
In a method to control a development process and an electrographic process, at least one developer station inks a latent image on a carrier with a toner. The toner is extracted from a mixture of toner and toner particles and wherein first toner is supplied to the mixture. A characteristic value is determined for a status of the mixture from a model calculation in which a toner exchange rate and an operating aging rate are linked. The development process is at least one of monitored, controlled, or regulated depending on the characteristic value. Also in a related method for controlling a development process, a characteristic value is determined for a status of the mixture from a model calculation in which a change of a toner consumption rate for the toner within a time interval during operation of the developer station and a time constant are taken into account. At least one of monitoring, controlling, or regulating the development process depends on the characteristic value.
