(4) 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).
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 electrostatic latent image visible.
