A fine grain powder metering unit for fine-grained powders combines the volumetric metering mode with the weighing mode, using for pre-metering 95-99% of the required quantity a volumetric drawer which is then emptied into the tray of a precision scale where a low-flow feeder feeds the powder for metering the final 1-5%, so as to combine the advantages of both metering modes and quickly achieve a metering with high accuracy and repeatability, automatically and with a simple and reliable structure.

A distribution assembly for product delivers and deposits a precise quantity of product on a support. The assembly includes a cylinder, a piston, displaced in the cylinder by an actuator, a route for taking in the product, an ejection head with a slide valve movable between a first closed position and a second open position, and an outlet nozzle, a preparation chamber, a transfer passage, connecting, selectively the preparation chamber with the outlet nozzle. When the cylinder comes towards the support, the physical contact with the support moves the slide valve from the first position to the second position and triggers delivery of the product, pushed by the piston, via the transfer passage. When the piston arrives at the forward end of range, the piston moves the slide valve from the second to the first position, closing the passage for the product via the transfer passage.

A developer supply container includes a rotating container for conveying a developer and an intermittent regulator for intermittently supplying gas into the rotating container and regulating an internal pressure of the rotating container. A fixed amount of gas is intermittently supplied by the intermittent regulator to the gas mixing space and is discharged from the powder discharging port after the fixed amount of gas is mixed with the developer. Since the intermittent regulator can periodically supply the fixed amount of gas to the gas mixing space, the fixed amount of gas ensures a stable gas pressure inside the developer supply container. The developer supply container can continuously and stably replenish the developer into the image forming device under any storage or operating environment. The air pressure of the developer supply container is maintained at a stable level and a high precision replenishment amount of the developer is achieved.
