Abstract
An image adjusting apparatus being provided in a copying machine capable of performing a copy of an original by using a photosensitive body in two or more copying modes, includes a unit for sensing a toner density of an image formed on the photosensitive body, a unit for deriving a function in accordance with each of the two or more copying modes if a control voltage influencing the toner density is changed, and a unit for setting the control voltage to be a voltage value obtained based on a predetermined reference toner density and the function derived by the deriving unit. The function stands for a relation between the changed control voltage and the toner density sensed by the sensing unit.
