<p>PURPOSE:To obtain the electrophotographic device and the toner utilized where generation of ground fogging is prevented even at the time of consecutive printing over a long period, in the device where the magnetic toner recovered to a cleaner is returned again to a developing part for recycling. CONSTITUTION:The electrophotographic device is provided with a negative charge electrophotographic photosensitive body 25 where binder resin is constituted of polycarbonate base resin, a toner hopper 30, negative charge magnetic toner 31 where binder resin is constituted of styrene acrylic base resin, an electrode roller 32 disposed with a space between the photosensitive body 25 and forming a toner image on the photosensitive body, a transferring device where the toner image is transferred while pressing paper into contact with the photosensitive body 25, the cleaner 39 where the remaining toner on the photosensitive body is cleaned and a cycling mechanism where the magnetic toner 31 recovered to the cleaner 39 is returned to the toner hopper 30. Thus, the device and the magnetic toner utilized can be obtained where generation of the ground fogging is prevented even in consecutive printing over the long period, as the toner recycling device.</p> |
