PURPOSE:To provide the titled apparatus which is excellent in interchangeability of parts by such an arrangement wherein a means for establishing conditions for electrification of heat generating resistors is mounted on a ceramic plate in which heat generating resistors are to be formed, and such conditions for electrification that correspond to an average resistance value of the array of heat generating resistors can be set. CONSTITUTION:On a ceramic plate 5, a strap wire 7 is provided as a means for setting conditions for electrification, and the wire is cut off according to an average resistance value of an array 6 of heat generating resistor at the time of manufacture of the ceramic plate 5. Such an information whether the strap wire 7 is cut off or not is supplied to a record control circuit 2, and a counter circuit 8 counts standard pulses 9 and generates print pulses 10. In response to image input signals, an electrification control circuit 3 supplies a current to a heat generating resistor 6 for the time of width of the print pulse 10. |
