Static latent image forming block
This block consists of 2 steps to form a static latent image on the photosensitive drum.
●
Step 1: Primary charging
Before forming a static latent image, the photosensitive drum surface should be charged
negatively.
This product employs the method to charge the photosensitive drum directly from the primary
charging roller, applying the DC negative bias in order to negatively charge the photosensitive
drum surface.
