Narrative:

Got ATIS information from homer radio; and called in for a traffic advisory while taxiing to the runway. Runway 22 at homer only has taxiways near the approach end of runway 4. A back-taxi on the runway is required to use runway 22. I was at the middle taxiway. Homer radio provided the traffic advisory; and stated there were two float planes on the downwind to land on the lake (which has an opposite traffic pattern from runway). I had both of the float planes in sight; and they were not going to be a factor. I scanned the runway and the final approach path of runway 22 and saw no aircraft. I announced that I was back taxiing on runway 22; and pulled across the hold short line. My nose had just entered the runway when I saw an airplane coming down runway 22 on the roll out. He pulled off on the taxiway prior to the one I was using and called clear of the runway.I have no idea how I didn't see him. I was very surprised; and can't remember if his lights were on. Contributing factors may have been that I was in a slight hurry because I was running about 10 minutes behind schedule; and that flight was my sixth departure from homer that day so a little fatigue came into play as well. Complacency was probably also a factor. Homer radio called out the traffic; but I did not hear them mention the aircraft on roll out on 22; if they even mentioned it; which I don't believe they did. I also scanned the runway pretty diligently before entering the runway; but somehow I still didn't see that aircraft. White aircraft are pretty difficult to see when going over large white runway stripes. The runway is also; convex; which can make traffic father down runway 22 harder to see.I have been an advocate; for a long time; about putting in a taxiway that extends full length down runway 22. The traffic flow on runway 22 can get pretty intense when aircraft are landing and multiple aircraft are waiting to back taxi; and can cause people to rush to back taxi in-between aircraft in the pattern. In the future; I'll slow down; and fight complacency with a good traffic scan. If that had been an aircraft on takeoff; the outcome of this event could have been very different.
