[5] Laser exposure Expose photoconductor to a laser beam to develop electrostatic latent image.
[6] Developing The toner, agitated and negatively charged in the developer mixing chamber, is attracted onto the
electrostatic latent image formed on the surface of the photoconductor. It is thereby changed to a
visible, developed image.
[7] 1st transfer A DC positive voltage is applied to the backside of the transfer belt, thereby allowing the visible,
developed image on the surface of each of the photoconductors (Y, M, C, and K) to be transferred
onto the transfer belt.
[8] 2nd transfer A DC positive voltage is applied to the backside of the paper, thereby allowing the visible,
developed image on the surface of the transfer belt to be transferred onto the paper.
[9] Separation The paper, which has undergone the 2nd transfer process, is neutralized so that it can be properly
separated from the transfer belt by the paper separator claws.
[10] Transfer belt cleaning Residual toner on the surface of the transfer belt is collected for cleaning by cleaning blade.
[11] Fusing The visible toner image transferred onto the surface of the paper is melted by the heat of the fusing
roller and fixed to the paper by pressure.
[12] Photoconductor cleaning The residual toner left on the surface of the photoconductor is scraped off.
