PURPOSE:To perform transcription and recording on a recording paper by developing after forming a charge latent image on a recording conversion medium, by using apyroelectric film for the recording conversion medium. CONSTITUTION:A switch 12 is connected for a time of about 10msec, and the heat is generated by a nichromate vapor deposited resistance film 9 formed on the surface of a forsterite substrate 8 to heat up a composite pyroelectric film 13. The surface potential reaches the maximum value of about 240V in about 10sec after the heating, and is then reduced down to about 15V in about 80sec after the maximum value. Then a toner electrified by a magnetic brush is sprayed in about 10sec after the second heating of about 10msec. Thus the toner sticks to the area of only 1cmX 1cm. The reflection factor of light is about 15% at the area. |
