Summary:PURPOSE:To obtain an excellent recorded image by preventing fluctuations in a potential from locally occurring in a recorded image and a reference toner image. CONSTITUTION:In this image recorder provided with a photosensitive body capable of forming plural image regions in a cycle, a region means setting plural image regions in a cycle of the photosensitive body and reference toner image regions among the image regions, a means detecting the density of the reference toner image, and a means controlling a toner concentration by based on the result of the detected reference toner image density, the build-up timing of the discharge current of a high voltage power source for main and auxiliary electrostatic charging devices 54 is set in a position between the image regions and except the reference toner image region, with the signals of the position detecting means 51 of the photosensitive body and an image region and reference toner image region setting means 52.
