The image forming apparatus includes, a movable first image bearing member on
which a toner image is formed; and a movable second image bearing member which
is brought into contact with the first image bearing member and to which the toner
image on the first image bearing member is transferred, in which the toner image
on the second image bearing member is transferred onto a transferring material,
a dot-shaped dot image formed of a toner different from the toner image is formable
on the first image bearing member, and the dot image is variable according to a
condition upon forming the toner image on the transferring material. Thus, there
is provided an image forming apparatus capable of forming a final image with a
high quality in a stable manner independently of a selection of a type of transferring
materials or image quality mode as well as suppressing an image streak occurrence.
