Do we roll or slide eraser to remove the pencil work from note book?
Yes, because they work by shedding rubber to discard the removed graphite. That shedding requires a mechanical rubbing action, and that will inevitably force some graphite deeper into the paper. ... Rolling, or dabbing, is the preferred way to use kneadable erasers, because they absorb graphite.

How do erasers erase?
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.
