An image forming apparatus includes an exposure device for exposing an electrically charged surface of an image bearing member to light to form an electrostatic image; a developing device capable of collecting a transfer residual developer remaining on the image bearing member; a transferring device for transferring a developer image from the image bearing member onto a transfer medium at a transfer position; and a controller for executing, during non-image formation, a developer collecting mode in which a developer of an opposite polarity is collected into the developing device by driving the image bearing member and by causing the developer carrying member to stop its rotation or rotate at a speed slower than a rotational speed thereof during image formation while generating a potential difference capable of transferring the developer of the opposite polarity from the image bearing member onto the developer carrying member.
