Abstract An image forming apparatus is provided with an image bearing member bearing a toner image thereon, a toner image forming device for forming the toner image on the image bearing member, a transferring member for transferring the toner image borne on the image bearing member to a recording medium being moved, a cleaning member for electrostatically removing the toner adhering to the transferring member, and an electric field forming device for forming an electric field between the transferring member and the cleaning member, wherein when the greatest length of the image formable by the toner image forming device in a direction orthogonal to the direction of movement of the recording medium is defined as L, and the length of the transferring member is defined as L, and the length of an area in which the electric field is formed is defined as L, the relation that L>L>L is satisfied.
