(5) Developing
Toner is attracted to the electrostatic latent image on the image drum surface to convert it into a visible
toner image. Developing takes place at 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 part (low-potential part) of the image drum at the contact between the
image drum and the developing roller, making the electrostatic latent image visible.
(6) Transfer
The transfer roller is composed of conductive sponge material and is designed to make the image drum
surface and the paper closely into contact.
Paper is placed over the image drum surface, and a positive charge, opposite in polarity to the toner, is
applied to the paper from its reverse side.
The application of a high positive voltage from the power supply to the transfer roller causes the positive
charge induced to the transfer roller surface to be transferred to the paper at the contact between the
