Abstract:
A color image forming apparatus comprising: a first development device which develops an electrostatic image on a first image bearing member with toner of color other than black; 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 bearing member with black toner so as to form a toner image and collects the toner on the second image bearing member; 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, wherein the position of the second transfer member to the second image bearing member in the moving direction of the image receiving member is in the downstream side relative to the position of the first image bearing member of the first transfer member.
