The binary X-ray pulsar A0535+262 was observed with the Suzaku X-rayobservatory, on 2005 September 14 for a net exposure of 22 ksec. The source wasin a declining phase of a minor outburst, exhibiting 3--50 keV luminosity ofabout $3.7 \times 10^{35}$ ergs s$^{-1}$ at an assumed distance of 2 kpc. Inspite of the very low source intensity (about 30 mCrab at 20 keV), its electroncyclotron resonance was detected clearly with the Suzaku Hard X-ray Detector,in absorption at about 45 keV. The resonance energy is found to be essentiallythe same as those measured when the source is almost two orders of magnitudemore luminous. These results are compared with the luminosity-dependent changesin the cyclotron resonance energy, observed from 4U 0115+63 and X 0331+53.
