ABSTRACT:
An image forming apparatus includes a first image forming station including an image bearing member, developing means for developing an electrostatic image formed on the image bearing member with toner, wherein the toner remaining on the image bearing member after a developed image is transferred, is collected by the developing means; a transfer rotatable member; a first cleaning member for removing toner from the transfer rotatable member; a second image forming station including an image bearing member, developing means for developing an electrostatic image formed on the image bearing member with toner, a second cleaning member for removing the toner remaining on the image bearing member after a developed image is transferred, wherein the second image forming station is disposed downstream of the first image forming station and upstream of the second cleaning member with respect to a peripheral moving direction of rotation of the transfer rotatable member; and collection control means for a control operation to collect, by the second cleaning member of the second image forming station, the toner discharged to the transfer rotatable member from the first image forming station during a non-image-formation period.
