2. DESCRIPTION OF OPERATION
3. Image development
Toner is attracted to the electrostatic latent image on the image drum surface, then
the electrostatic latent image changes to toner image.
1. As the roller on the supply spot of toner rotates while scrubbing the image-
developing roller, fiction electricity occurs between the image developing
roller and toner; toner is attracted to the image-developing roller.
2. The toner that has been attracted to the image-developing roller is dropped
down to the developing plate to make a thin toner film on the image
developing roller side.
3. The toner is attracted by the exposed part (Low electrical potential part) of
the image drum when the image drum contact the image developing roller,
so as to see the electrostatic latent image.
Note! The necessary bypass voltage in image processing is impressed on the
toner feeding roller and image developing roller as show below.
