Erasers pick up graphite particles, thus removing them from the surface of the paper. Basically, the molecules in erasers are 'stickier' than the paper, so when the eraser is rubbed onto the pencil mark, the graphite sticks to the eraser preferentially over the paper. Some erasers damage the top layer of the paper and remove it as well. Erasers attached to pencils absorb the graphite particles and leave a residue which needs to be brushed away. This type of eraser can remove the surface of the paper. Soft vinyl erasers are softer than the erasers attached to pencils, but are otherwise similar.
The sticky rubber in the eraser grabs and holds on to the graphite particles. Erasers work because of friction. ... As the rubber grabs the graphite particles, small pieces of combined rubber and graphite get left behind. That's the “stuff" you brush off of your paper when you're finished erasing.
