Image transfer method and apparatus in which scratches due to entrainment
of particles on an image carrier for a toner image having maximum
spectroreflectivity at a wavelength of 550 nm do not produce perceptible
flaws in resulting images transferred to a recording medium, since images
formed with toner of maximum spectroreflectivity at 550 nm on white
recording medium are difficult for human eyes to discern. When cleaning
residual toner from transfer belts, reverse bias voltage is applied to at
least one transfer roller, the peripheral velocity of the photosensitive
drum on which a yellow toner image having maximum spectroreflectivity at
550 nm is formed is allowed to differ from the transfer velocity of the
transfer belt, and at least the photosensitive drum on which the yellow
toner image of maximum spectroreflectivity at 550 nm is formed is
detached from the transfer belt.
