Interesting stuff.

In classic xerography, yes, the toner is moved around electrostatically. But it also needs to have magnetic properties (either intrinsically or by means of developer) to form a magnetic “brush” which is presented to the drum. Think of iron filings mixed with toner on a piece of paper and a magnet on the other side. The right static charge will be able to pull the toner out while leaving the iron filings behind.
