Abstract
Disclosed are an image forming method that removes adhered material from a latent image carrier and then forms an image on the latent image carrier, and an image forming apparatus that employs this method. The image forming apparatus includes: a developing unit for developing the latent image on the image carrier by toner and for collecting residual toner on the carrier; a transfer unit for transferring to the developed image a sheet; a removing mechanism for removing material that adheres to the carrier; a drive mechanism for rotating the carrier; and a controller for selectively executing an image forming mode, to control the individual constituent units, and an adhered material removal mode, to permit the removing mechanism to remove the material that adheres to the carrier as it is rotated by the drive mechanism. The image forming method includes: a rotation start step, for initiating rotation of an endless latent image carrier; an adhered material removal step, for permitting an removing mechanism to remove material that adheres to the carrier during at least one rotation of the carrier following the initiation of the rotation; a charging step, for applying an electrical charge to the carrier; a latent image forming step, for forming a latent image on the carrier; a developing step, for developing the latent image on the carrier and for collecting residual toner from the carrier; and a transfer step, for transferring to a sheet a toner image on the carrier.
