Developing
Toner is attracted to the electrostatic latent image on the image drum surface,
converting it into a visible toner image. Developing takes place through the contact
between the image drum and the developing roller.
1
As the toner supply roller rotates while rubbing on the developing roller, a
friction charge is generated between the developing roller and the toner,
allowing the toner to be attracted to the developing roller (the developing roller
surface is charged positive and the toner, negative.)

Toner supply roller
2
The toner attracted to the developing roller is scraped off by the doctor blade,
forming a thin coat of toner on the developing roller surface.
3
Toner is attracted to the exposed portion (low-potential part) of the image drum
at the contact of the image drum and the developing roller, making the electro-
static latent image visible.
