Abstract
An image forming apparatus includes an image bearing member on which first and second electrostatic images are formed, a first developing device for developing the first electrostatic image on the image bearing member with a first toner, and a second developing device for developing the second electrostatic image on the image bearing member bearing the first toner image thereon with a second toner. The second developing device has a toner carrying member opposed to the image bearing member and carrying the toners thereon. The force with which the first toner, having mixed into the second developing device, is carried on the toner carrying member is smaller than the force with which the second toner is carried on the toner carrying member.
