One could construct toner particles with iron to result in at least two different particle types: one, where the iron was completely coated with some sort of insulator (e.g., plastic) and so unable to form electrical connections, and two, where the iron was not completely covered and able to form electrical connections. There are obviously a bunch of variations on the latter which would result in various partially conductive configurations.

I have no idea if any of these formulations actually exist.

Using electrostatics, you actually don't want conductivity through the material or it will all just equalize.

Think of the last time you've opened a box full of styrofoam packing peanuts.
