WET IMAGE FORMING METHOD AND ITS DEVICE

PURPOSE:To provide a wet electrophotographic method hardly deteriorating sharpness and occurring central-blank by mitigating solvent shock even when a comparatively large amount of concentrated toner is replenished to a developing liquid tank. CONSTITUTION:Two toner bottles 42a and 42b containing the concentrated toner having a different toner solid concentration, is installed in the developing liquid tank 40. One of the bottles contains the concentrated toner of a comparatively high solid concentration (15wt.%), so as to compensate for the toner solids consumed in copying, as much as possible, and the other toner bottle contains the concentrated toner of a comparatively low solid concentration (10wt.%) so as to reduce the solvent shock when a comparatively large amount of the solid toner is replenished in a short time. When a toner concentration detected by a sensor 46 is 50g/l or below, the toner is replenished from the latter bottle, and when the toner concentration is 50g/l to
