The primary charging bias is used to charge the surface of the photosensitive drum evenly to prepare
for image formation. The primary charging bias circuit generates the bias.
The developing bias is used to adhere toner to an electrostatic latent image formed on the
photosensitive drum. The developing bias circuit generates the bias.
The transfer bias is used to transfer the toner from the photosensitive drum onto the paper. The transfer
bias circuit generates the bias. The transfer bias is used to transfer the toner from the photosensitive
drum onto the paper. The transfer bias circuit generates the bias.
The fuser bias is used to stabilize the paper-feed and improve the print quality. The fuser bias circuit
generates the bias.
