Abstract:
A method for controlling concentration of a developer in a developing reservoir of a wet printer comprising the steps of:(a) counting image data output from a system controller to a laser scanning unit to form an electrostatic latent image on a photosensitive medium;(b) calculating an amount of a consumed toner supplied from the developing reservoir to the photosensitive medium during formation of a toner image, the calculated amount being based on a value counted in step (a) to form the electrostatic latent image;(c) supplying toner from a toner supplying unit into the developing reservoir to refill the amount of the consumed toner calculated in step (b); and(d) counting a number of paper sheets printed by a toner image corresponding to the electrostatic latent image, to calculate an amount of a consumed liquid carrier element which is supplied from the developing reservoir to the photosensitive medium to form the toner image, and supplying the calculated amount of the consumed liquid carrier element from a liquid carrier element supplying unit to the developing reservoir.
