摘要:
An image formation apparatus comprises an image bearing member, developing means for developing by use of toner the electrostatic image formed on the image bearing member, transfer charging means for transferring the toner image from the image bearing member to a transfer material in the transfer position, and separation means for de-electrifying said transfer material for separating the transfer material from the image bearing member. Then, after the toner image formed on the transfer material for the first time is fixed, the toner image is formed on the same transfer material for the second time. For this apparatus, modifying means is further provided for modifying the development conditions of the first toner image and the second toner image formed on the transfer material, and modifying the adhesive amount of fogging toner adhering to the image background of the toner image on the image bearing member. With the structure thus arranged, it is made possible to prevent the defective separation and re-transfer, and at the same time, to reduce the development fog as much as possible for a significant enhancement of image formation.

An image forming apparatus for forming an image on a recording material comprising: a plurality of processing devices for forming the image; a detector (163-2) for detecting at least a quantity of state relating to a control of the processing devices; an inference computer (801) for inferring, in accordance with the quantity of state, a quantity of control for use to control the processing devices.
摘要:
The present invention relates to an image forming apparatus having cleaning means (2) which frictionally contacts magnetic particles on a magnet roller (4) with an image bearing member in order to remove foreign matters adhered to the image bearing member, thereby preventing the deterioration of the image quality. According to the present invention, by slowly rotating the magnet roller (4) so that a portion thereof opposed to the image bearing member is moved in the same direction as a moving direction of the image bearing member, thus preventing the toner from overflowing and scattering out of the cleaning means (2). Further, when the non-magnetic toner is used, by providing a toner cavity on the magnet roller (4), the scattering of the non-magnetic toner can be prevented, whereby the parts in the apparatus is prevented from being contaminated by the toner.
