    Abstract: An image forming apparatus including an electrophotographic photoconductive member, a charging unit, a delivery unit and a cleaning unit. The charging unit is disposed in contact with the surface of the photoconductive member and the delivery unit disposed in contact with the surface of the charging unit. The delivery unit applies a layer of functional material to a surface of the charging unit and the charging unit in turn applies a layer of the functional material onto the surface of the photoconductive member. The cleaning unit is disposed in contact with a surface of the charging unit to clean the charging unit and reduce contamination of a surface of the delivery unit. The cleaning unit is disposed in an upstream direction of the delivery roller relative to a rotation direction of the charging unit.

    Abstract: A method and system for magnetic actuated mixing which use magnetic particles and magnetic field to facilitate the mixing for preparing latex emulsion. In embodiments, a suitable process includes dissolving a resin in an organic solvent, optionally adding a surfactant, adding a neutralization agent and water, adding magnetic particles, and subjecting the mixture to a magnetic actuated mixing to form a latex emulsion. In embodiments, the latex emulsion thus produced may be utilized to form a toner.

    Abstract: There is described an image forming apparatus including an imaging member having a charge retentive-surface for developing an electrostatic latent image thereon, a substrate and a photoconductive member disposed on the substrate. A bias charge roller for applying an electrostatic charge on the charge retentive surface to a predetermined electric potential is included in the image forming apparatus. The bias charge roller includes a first circumferential area in contact with the photoconductive member (CC[contact]), and a second circumferential area (CC[non-contact]) spaced a distance of from 1 μm to 1 mm from the photoconductive member. The image forming apparatus includes a power supply for supplying an oscillating voltage signal to the bias charge roller wherein the oscillating voltage signal has a frequency Am[fAC] and an amplitude Am[VAC]. The following relationship is met: (CC[contact]/CC[non-contact])≦(Am[fAC]/Am[VAC])≦(CC[non-contact]/CC[contact]) by the image forming apparatus.
