Abstract
A color image forming apparatus includes a first development device which develops an electrostatic image on a first image bearing member with toner of a color other than black so as to form a toner image; a first transfer member which forms a nip portion for nipping an image receiving member with the first image bearing member; a second development device which develops an electrostatic image on a second image bearing member with black toner so as to form a toner image; and a second transfer member which forms a nip portion for nipping the image receiving member with respect to the second image bearing member and transfers the toner image on the second image bearing member electrostatically to the image receiving member. The position of the second transfer member to the second image bearing member in the moving direction of the image receiving member is on the downstream side relative to the position of the first image bearing member of the first transfer member.
