Abstract: An image forming apparatus includes an image forming part, a transfer member, a carrying part, a control part, a contact/separation part that performs a separation operation through which the transfer member and the developer carrier become relatively separated, and a contact operation through which the transfer member and the developer carrier become in contact each other at a contact timing. Before the control part finishes transferring a developer image to a recording medium at a secondary transfer position, the contract/separation timing control part sets a separation timing, and the contact/separation performs the separation operation.

Abstract: In at least one implementation, a blank washer inspection process includes the steps of: applying at least one test particle to a blank; washing the blank having the test particle thereon; inspecting the blank after it has been washed to identify any test particle on the blank; and comparing any test particle identified in the inspection step to a threshold. The threshold may relate to a control property of the test particle. In at least some implementations, the control property is the size of the particle and a maximum size may be set as a threshold. Other control properties may be used. Further the test particles may include detection properties to facilitate identifying test particles and distinguishing among test particles in different groups.

Abstract: An image forming apparatus of the present invention is arranged to hold an intermediate transfer belt and a photoconductive drum out of contact with each other. In a non image formation process in a first mode, the intermediate transfer belt and the photoconductive drum are separated from each other upon completion of the image formation, thereby preventing contamination of the photoconductive drum due to back transfer. In a non image formation process in a second mode, the intermediate transfer belt and the photoconductive drum are separated from each other upon completion of the image formation, and then the intermediate transfer belt and the photoconductive drum are contacted with each other again upon completion of secondary transfer of an image. They are driven for a predetermined time with a speed difference therebetween, thereby abrading the surface of the photoconductive drum to refresh it.

Abstract: An image-bearing article used in liquid contact electrostatic printing (CEP) is formed from polymers that meet the requisite conformance and heat stability for the CEP process. Excessive absorption of toner carrier liquids by the image-bearing article in liquid CEP leads to the deterioration of the image-bearing article and reduces the useful life of the image-bearing article. The absorption of the toner carrier fluid may be controlled by the addition of oxides, silicone elastomers containing phenyl end groups, fluorosilicones or increasing the cross-linking density of the methyl silicones.
