To effectively use a toner consumed by toner ejection, for example, as a toner image for detecting color misregistration.

An image forming apparatus includes an ejection executing unit 121 for forcibly ejecting toner from a developing unit to form a toner image on a photoreceptor drum 1. In the process of transferring a toner image formed on the photoreceptor drum 1 by the ejection executing unit 121, a primary transfer roller 6 applies a first transfer bias (T103 to T104, T105 to T106) with a predetermined transfer efficiency to an intermediate transfer belt 8 in a predetermined area portion of the toner image, and applies a second transfer bias (T104 to T105) with a low transfer efficiency compared to at least the transfer efficiency of the first transfer bias, in a portion except for the predetermined area portion of the toner image.
