PURPOSE:To prevent the dislodgment of the toner once sticking to recording paper and to improve imaging quality by providing a heating element to the surface of a counter electrode facing a toner transfer part. CONSTITUTION:This recorder consists of the three layers; a transparent base 1, a transparent electrode 1b formed atop the base and a potoconductive layer 1c formed atop the transparent electrode. The transparent electrode 1b is biased to a negative voltage by a power source E1. The counter electrode 5 such as transfer roller electrode connected with a power source E2 is disposed to face the toner transfer part 3 and the heating element 5a consisting of a thin film is provided on the surface of the counter electrode 5 by vapor deposition of indium oxide In2O3 ('NESA(R)') film. The heating element is heated when several tens volts of AC or DC voltage is impressed thereto through electrodes 5b, 5c provided at both ends thereof from an electrode 6 for heating. The toner is, therefore, melted by the effect of the heating element and is tentatively fixed to the recording paper when the toner electrostatically charged to the polarity reverse from the voltage impressed to the counter electrode is transferred to the recording paper by the effect of the counter electrode in the toner transfer part. The dropping and resplashing of the toner are thereby prevented. |
