An object of the present invention is to provide an image forming apparatus that has an image bearing member, a moving member, transferring device for transferring an image formed on the image bearing member onto the moving member at a transferring position by applying a voltage thereto, and detecting device for detecting an image for density control and an image for gradation control on the moving member transferred from the image bearing member, wherein a density and gradation of the image formed on the image bearing member are controlled on the basis of a result of a detection by the detecting device, and wherein a voltage when the image for density control formed on the image bearing member is transferred onto the moving member and a voltage when the image for gradation control formed on the image bearing member is transferred onto the moving member differ from each other. In addition the image for density control is detected on the moving member before the density image passes through the transferring position, and the image for graduation control is detected on the moving member after the graduation image passes through the transferring position.
