The influence of the N_2-O_2 gas mixture upon the dust figure length of impulse surface discharges was studied by using the Dust Figure Method for the polbuschel region. Positive and negative standard wave-shape impulse voltage was applied to a needle electrode on an acryl resin plate with a backing electrode. The dust figure length was measured as the maximum length from the contact point of the needle electrode to the edge of the dust figure. The gas mixing ratio of N_2 to O_2 was varied systematically. The instantaneous voltage corresponding to the corona current pulse was obtained by observing the impulse voltage and corona current at the same time. As a result of the experiment, we reported 1） characteristic curves of the dust figure length versus the gas mixing ratio of N_2 to O_2 for each polarity in relation to instantaneous voltage, 2） the polarity effects of the gas mixture on the dust figure length and on the shape of the characteristic curve and 3） the pattern of the dust figure as affected by the consistency of each gases.
