TONER, IMAGE FORMING DEVICE AND PROCESS CARTRIDGE Russian patent published in 2015 - IPC G03G9/08 

FIELD: printing.

SUBSTANCE: group of inventions comprises a toner, a process cartridge and an image forming device. At that the toner comprises a binder resin, a colorant and a surface additive treated with silicone oil, and the surface additive treated with silicone oil comprises unbound silicone oil, and the total amount of unbound silicone oil is from 0.2% by weight to 0.5% by weight relative to the toner, and the toner has an average circularity of from 0.96 to 1. The image forming device comprises: a primary transfer unit configured to transfer the visible image from the surface of the latent image bearing element to the intermediate transfer element; the unit of removal of toner from the latent image bearing element, configured for removal by means of squeegee of the latent image bearing element of the toner remaining on the surface of the latent image bearing element after transferring the visible image by the primary transfer unit; a secondary transfer unit configured to transfer the transferred visible image from the intermediate transfer image to the recording medium; and the unit of removal of toner from the intermediate transfer element, configured to remove by means of the squeegee of the intermediate transfer element the toner remaining on the surface of the intermediate transfer element after transfer of the transferred image by the secondary transfer unit. The process cartridge comprises: a latent image bearing element and at least one developing unit configured to develop the latent image, formed on the latent image bearing element using the toner, and the developing unit is combined with the latent image bearing element.

EFFECT: creation of inexpensive electrophotographic toner, an image forming device and a process cartridge, for all of which the usability of the spherical toner to cleaning in any environment is improved, the operational durability of the latent image bearing element is increased, the sediments on the developing element are prevented, and high quality images are formed.
