I doubt the CCD generates enough of an electrical
field to attract dirt. They are all low voltage
devices. Monitors attract dirt but thay have 25KV
going through them. I think the problem is caused by
three things. First is interchanging lenses. Second
there is beak-in dust (mostly metal) and finally there
is zooming and focusing which pushes air in and out of
the body. This last one is probably the most
significant IMHO and affects even fixed lens cameras.
