Abstract (en)
A toner image transferring device is applied to, for example, an electrophotographic printer for electrostatically transferring a charged toner image from a photosensitive drum (10) to a sheet or paper (P), and comprises a transfer charger (16) disposed near the drum (10) to form a clearance therebetween for feeding an electric charge to the sheet or paper through which the sheet or paper is passed, an electric source (38) for supplying an electric energy to the transfer charger to give the sheet or paper an electric charge having a polarity opposite to that of the toner image, and a controller (40) for controlling the electric energy output from the electric source (38) to the transfer charger (11) so that a leading edge of the sheet or paper can be prevented from being excessively charged.
