Abstract
An image processing apparatus includes first latent image formation section for forming an electrostatic latent image corresponding to an image of a document on a photoconductor by projecting light reflected from the document, and second latent image formation section for forming an electrostatic latent image on the photoconductor responsive to electric signals outputted from an image sensor. The image processing apparatus further includes first and second developing units for developing the electrostatic latent image formed on the photoconductor so as to form a toner image thereon by making toner adhere to unexposed and exposed portions of the photoconductor, respectively, and transfer charger for transferring the toner image formed on the photoconductor onto paper. A controller enables the first developing unit to operate and applies a voltage of a polarity corresponding to the enabled developing unit to the transfer charger when an electrostatic latent image is formed on the photoconductor by the first latent image formation section, and enables the second developing unit to operate and applies a voltage of a polarity corresponding to the enabled developing unit to the transfer charger when an electrostatic latent image is formed on the photocondcutor by the second latent image formation section.
