An image forming apparatus comprising: an image carrier; a toner image formation mechanism for forming a toner image on the image carrier; a transfer member, provided at a position at which the transfer member can be pressed against the image carrier, configured to transfer the toner image, formed on the image carrier, onto a transferred material; and a control section, characterized in that the image forming apparatus further comprises a detection device configured to detect a toner attachment amount of the toner image formed on the image carrier, and the control section comprises: an avoidance judging section configured to judge whether or not avoidance of a pressed region should be performed when a toner image for image formation is formed on the image carrier, the pressed region serving as a region located on the image carrier and being pressed against the transfer member from the end of a previous image forming operation to the start of a present image forming operation; and an avoidance continuation judging section (72; 74) configured to judge the necessity for continuation of the avoidance being operated when it is judged by the avoidance judging section that the "avoidance should be performed", wherein the avoidance continuation judging section (72; 74) comprises: a recognition part (721; 741) configured to recognize the position of the pressed region; a formation part (722; 742) configured to form a detection toner image on the pressed region by the toner image formation mechanism; a detection part (724; 743) configured to detect, by the detection device, a toner attachment amount of the detection toner image formed on the pressed region; and a decision part (724; 744) configured to decide the necessity for continuation of the avoidance based on the toner attachment amount. an image carrier; a toner image formation mechanism for forming a toner image on the image carrier; a transfer member, provided at a position at which the transfer member can be pressed against the image carrier, configured to transfer the toner image, formed on the image carrier, onto a transferred material;
