I would call that 'Triplicate Paper' as it gives you three for each one you write!  The clue is in Karen's answer - its called a 'carbon copy' because there's a thin layer of carbon on the back of each white & yellow sheet (at least traditionally).  This means that as you press down with your pen on the top sheet, the pressure causes the carbon to come off the back of the white, and on to the pink...

Also see http://en.wikipedia.org/wiki/Carbonless_copy_paper
I thought it may have moved on from the traditional carbon, thanks LeeE!

They use NCR (No Carbon Required) paper.
You don't get dirty fingers from the back of this paper any more. The lower layers are made black by the pressure from the top and the construction of the two toughing faces.

Fax paper is heat sensitive - applying heat to it changes it's colour.  Modern fax machines are likely to be ink-jet or laser though.
