Abstract:
1. A transparent toner image printing apparatus comprising: a photosensitive member; an exposing device configured to expose said photosensitive member based on image information to form an electrostatic image; a developing device configured to develop the electrostatic image on said photosensitive member to form a transparent toner image using a two component developer; a voltage applying device configured to apply a DC voltage biased with an AC voltage to said developing device; a transferring device configured to transfer the transparent toner image on said photosensitive member onto a non-preprinted sheet or a preprinted sheet; a fixing device configured to heat-fix the transparent toner image on the non-preprinted sheet or the preprinted sheet in a fixing nip thereof; a selecting device configured to select one of a first mode in which the transparent toner image is formed on the preprinted sheet and a second mode in which the transparent toner image is formed on the non-preprinted sheet; and a controlling device configured to control an operation of said voltage applying device, wherein an amplitude of the AC voltage in the first mode is larger than an amplitude of the AC voltage in the second mode due to said controlling device.
