DEVELOPER FEED CONTAINER, DEVELOPER FEED SYSTEM AND IMAGING DEVICE Russian patent published in 2016 - IPC G03G15/08 

FIELD: physics, photo.

SUBSTANCE: claimed invention relates to developer feed container to be coupled with developer intake device, developer feed system with said intake and said container and to imaging device. Claimed set of inventions comprises developer feed container, developer feed systems and imaging devices. Note here that developer feed container includes the developer intake part, venting element to allow entry and exit from said intake part. Note here that said container comprises the parts that follow. Part to contain the developer. Outlet to discharge the developer from the latter towards said intake part. Part to take up the motive force from said developer intake part. Pump part to be driven by said motive force tale up part to reiterate discharge and suction via said discharge outlet. Developer feed container side is provided with pump part to suck air from inside the developer intake part towards developer containing part and discharges air therefrom towards developer intake part. This makes the filter apply the reverse filter cleaning effect in suction cycle to rule out the filter clogging.
