Laser marking machine radiation harmful to the human body?

Radiation, but it will not have any effect on our body, if you understand its working principle will understand, the laser is only a small part of its work, the main radiation should come from the internal "developer rollers" and "drum center" The main radiation should come from the internal "developer rollers" and "drum core", "transfer electrode wire" and "fixer", all of which will be filled with a very strong voltage. So I think there must be radiation!
