Abstract: In an example of a method for reducing contamination, a purified imaging oil is formed by filtering an imaging oil through an imaging oil filter, and then filtering the imaging oil through a polar absorbent filter. A surface of an amorphous silicon photoconductor of a liquid electrophotographic printing apparatus is maintained by periodically applying the purified imaging oil to the amorphous silicon photoconductor.

Abstract: An image forming apparatus includes an image bearing member configured to bear a toner image formed using a liquid developer containing toner particles and a carrier liquid, a transfer member, an input portion into which information on a kind of a recording material is inputted, an adjusting device configured to adjust an amount of the carrier liquid of the toner image, and an executing portion configured to execute an operation of the adjusting device depending on the information when the toner image is in the adjusting position. The executing position executes either of a plurality of operations including a first operation in which the amount of the carrier liquid of the toner image is increased, a second operation in which the amount of the carrier liquid is decreased, and a third operation in which the amount of the carrier liquid is not adjusted.

Abstract: There is provided a liquid consuming apparatus including: a tank having a liquid storing chamber, an erected wall through which the liquid inside the liquid storage chamber is visible from outside of the tank, and an inlet which is formed to penetrate through the erected wall and via which the liquid is poured into the liquid storage chamber; a liquid consuming section which consumes the liquid stored in the liquid storing chamber; and a cover. A transmitting section and a checking section are formed in an upper surface, of the cover, under a condition that the cover is in the exposure position, the transmitting section configured to transmit information optically to a user of the liquid consuming apparatus and the checking section configured to prevent the liquid moving on a particular surface of the cover from arriving at the transmitting section.

Abstract: A binary ink developer assembly includes a plurality of rollers, gears, and end caps. The rollers are in contact with each other to form a nip. Each roller includes a plurality of bearings. The gears include gear teeth. A respective gear has an involute tooth profile and applies a gear force at a pressure angle corresponding to the involute tooth profile to rotate at least one roller. The end caps are coupled to the bearings. At least one slot arranged to form a slot angle substantially equal to the pressure angle and to receive a respective bearing to support a respective roller.
