This article is crap.
Photosensitve drum has a high voltage that is provided by the high voltage
power supply that charges the drum opposite of what the laser beam is
charged,
Since when have photons had charge?
so that the laser will charge dots on the drum that will form
the image of what is to be printed on the drum and is charged this way by
the primary corona wire.
The laser doesn't charge the drum, and the image forming mechanism of
the drum coating isn't even mentioned.
