Abstract
The image forming apparatus of the present embodiment has two limiters composed of a conventional high order limiter and a low order limiter, and carries out control to switch the limiter according to a temperature and a humidity so as not to reach a image contrast potential equal to or greater than those limiters. Carrier development can occur if image formation is performed in a state where the image contrast potential is high. Therefore, by providing a low order limiter as in the present embodiment and carrying out control so as not to exceed the low order limiter at the time of the image formation, an occurrence of the carrier development can be suppressed, and an image density can also be within a prescribed range.
