[1] The difference in potential between the drum surface and the developing sleeve causes toner to adhere to the latent static image on the drum, turning the image
into a visible image.
[2] The bias voltage applied to the transfer roller causes the toner to move from the drum to paper.
[3] The cleaning blade in contact with the drum scrapes off the residual toner from the drum.
