Abstract
An electrophotographic image forming apparatus for transferring a visible toner image formed on a photoconductive body onto an intermediate transfer body primarily and transferring the toner image transferred on the intermediate body onto a paper secondarily is disclosed. In the electrophotographic image forming apparatus, the toner remaining on the photoconductive body is removed by a first cleaner blade after the primary transfer, and the toner remaining on the intermediate transfer body is removed by a second cleaner blade after the secondary transfer. A contact pressure of the second cleaner blade to be applied to the intermediate transfer body is set to be larger than a contact pressure of the first cleaner blade to be applied to the photoconductive body.
