An image forming apparatus includes an image bearing member; an image forming portion for forming a toner image on the image bearing member, the image forming portion being capable of forming an image to be formed on a recording material and forming a control image for controlling an image density at a position adjacent to the image to be formed on the recording material; an intermediary transfer member rotatable while carrying the toner image transferred from the image bearing member; a transfer member for forming a transfer portion where the toner image is to be transferred from the intermediary transfer member onto the recording material; an electrostatic cleaning member for electrostatically removing the toner deposited on the transfer member; a density detecting portion, provided upstream of the transfer member with respect to a rotational direction of the intermediary transfer member, for detecting a density of the control image transferred on the intermediary transfer member; an adjusting portion for adjusting an image forming condition of the image forming portion depending on an output of the density detecting portion; and a charge amount changing portion for adjusting a charge amount of the control image transferred onto the intermediary transfer member.
