<p>An image forming apparatus (100) which forms an image on an image carrier (1) along with rotation of a developing sleeve (41) that carries a toner and carrier contained in a two-component developer, comprises: forming means (110) for forming a density detection toner image on the image carrier (1) using the toner carried by the developing sleeve (41); detection means (12) for detecting a density of the density detection toner image formed; prediction means (110) for predicting a toner charge amount in the two-component developer; correction means (110) for correcting the toner charge amount in the two-component developer using a value obtained from a relationship between the toner charge amount predicted and the density of the toner image that is detected; and control means (110) for, when forming the density detection toner image, controlling to increase a development efficiency, compared to image formation based on image data.</p> |
