CONTROL APPARATUS AND METHOD, IMAGE FORMING APPARATUS AND SYSTEM, AND COMPUTER READABLE MEDIUM

摘要

A control apparatus includes the following elements. A toner density specifying unit specifies a toner density in a developer stored in a developing device. A toner density controller performs control such that the toner density approximates a predetermined toner density target value. A first calculator calculates a first value corresponding to an image density of an image to be output after a first timing. A correction amount specifying unit specifies a correction amount for the toner density target value at the first timing. When the condition that an absolute value of a difference between the first value and a second value is greater than a predetermined threshold is satisfied, the correction amount specifying unit specifies a smaller correction amount for the toner density target value, compared with when the condition is not satisfied. A correcting unit corrects the toner density target value on the basis of the correction amount.
