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.
