摘要： This invention relates to an image forming apparatus which forms an image on a transfer medium using a two-component developing agent by electrophotography. An image forming apparatus according to this invention includes a potential sensor which measures the charging potential on an image forming body and a patch density sensor which detects the toner attraction amount of a patch image. In the image forming apparatus, a toner charge amount Qt (&mgr;C/g) is calculated from the potential of a patch image before and after development detected by the potential sensor and the image density of a developed patch image detected by the patch density sensor, and image formation is performed by setting image formation conditions based on the calculated toner charge amount Qt. To set the image formation conditions, a table which stores in advance an image formation condition corresponding to the toner charge amount Qt is used.
