Abstract
A method and an apparatus for controlling toner density detection in an electrophotographic-type image forming apparatus in which the control of various parts can be performed easily, the image forming process can be effectively done without deteriorating the productivity of the copying operation, the number of contacting/detaching operations of the transferring belt apparatus can be made small (minimized), and the toner can be prevented from dispersing whereby the reliability of controlling the toner density detection can be raised. In such a method and apparatus for controlling the toner density detection, the time interval of the transferring process is established to either a long interval or a short interval. When the time interval of the transferring process is the long interval, a transferring belt apparatus is detached from a photosensitive body, a standard density pattern is formed on the photosensitive body, and the density of the standard density pattern is detected by a density detecting unit. On the contrary, when the time interval of the transferring process is the short interval, the above-mentioned standard density pattern is not formed at all.
