I am going to guess that is an actual black backdrop or posterboard, minimal lighting on the backdrop, and then using levels in photoshop to make it true black. Thats how I did it on:
and
Thats just my thoughts on it. Hopefully Irene will give you guys some insite.
Get some black velvet for your backdrop. It absorbs very well. The lighting overall is pretty crappy on this but it shows how easy it is to do. All that I used is a yard of quality black velvet from the fabric store. The "figure" is literally sitting right on it, on top of a chair. The velvet is draped in such a manner that it creates a curve in the background, so the light hits all of it at an angle.

Exactly! Use a black background and watch your lighting.
If the amount of light on the BG is 3 stops (or more) below the amount of light on the subject the BG will be black.
Conversely, if the BG is 3 stops brighter than the subject then it will be white.
Black cloth (velvet, felt) will help tremendously in making the BG turn out black.
This is a very early entry of mine, but it's hot lights and the black is a black T-shirt turned inside out
The BG here is a piece of fake black fur fabric with a pattern in it to catch the light just a little bit, but very little light in on the BG. There is light on her shirt which is also black so it shows up.
