Abstract

PURPOSE:To obtain a recording device which can prevent the occurrence of the variance of the recording concentration which is caused by the revolution of a magnetic roll and perform the recording at a high speed, by providing a means that applies the control voltage to a back electrode in accordance with the revolving position of the magnetic roll. CONSTITUTION:The recording voltage pulse (b) obtained by amplifying the image signal (a) through an amplifier 9 is applied to a recording electrode 8. A back electrode 16 is set at the lower side of the electrode 8 and opposite to the lower edge part of the electrode 8. A recording medium 17 is transported toward an arrow D and between the electrode 8 and the electrode 16. A revolving position display plate 11 is attached to a rotary shaft 10 of the roll 2, and the grooves 12 of an equal number to the magnetic poles on the outer circumference surface of the roll 2 are provided to the plate 11 and in accordance with these magnetic poles. Then the position of each groove and then the position of each magnetic pole are detected by a detector, and the control voltage (d) which varies according to the revolving position of each magnetic pole is applied to the electrode 16. Thus the effect of the recording concetration which is caused by the change of the state of a toner chain based on the shift of each magnetic pole can be compensated.
