Abstract (en)
In a method for the development of electrostatic images an apparatus as described in figure 1 is used, wherein said apparatus comprises a counter means (10) which functions automatically to register the number of copying cycles in which a batch of developer material (15) is used and to yield signals indicative of the registered number, and an electronic control means (11) which functions in dependence upon such signals automatically to control the voltage biasing of an applicator (14) so that in the course of the use of developer material (15) of said batch for developing a plurality of latent images such voltage biasing is varied in a way which at least partly compensates for variations in the developing capability of said developer material (15).
