1 Charging
The photosensitive drum surface is
negatively charged with a static
charge.

Toner is brought in close proximity

2. Most color models use a transfer system in which the toner first transfers from the photosensitive drum to an intermediate transfer belt, then from the belt to the paper.
4 Transfer
The photosensitive drum is brought
into contact with the paper* and a
positive charge is applied from
behind, transferring the toner onto
the paper.
5 Fixing
Heat and pressure are applied to fix
the toner to the paper.

3. Breakthrough
Comparison of the Dry Mono-Component Jumping Method and
the Two-Component Method
Brand names and trademarks
Canon broke with convention and did away with the concentration adjustment
mechanism, essential for the two-component method that had been employed up to
that time and made use of a conductive toner and iron powder. In its place, Canon
announced the NP-200J, which employed a dry mono
jumping-development approach. This new method
copied images by accurately applying an insulating toner with a small particle size of
several micrometers, or several millionths of a meter, onto the photosensitive drum
