Toshiba D2505 Developer Powder 6LJ83445000 Black 200g

Carrier Refill for Mono e-STUDIO Engines

The D2505 developer powder is the black carrier material that refills the developer unit in Toshiba mono e-STUDIO copiers. Toshiba supplies 200 g in a sealed foil bag under part number 6LJ83445000. The carrier beads hold the triboelectric charge that transfers toner to the photoconductor.

Developer is distinct from toner. The magnetic carrier moves toner through the developer unit onto the drum. Coating wear and toner attrition degrade the charge over time. That degradation shows as background fog, weak density or toner scatter. A full drain and refill restores the specified carrier-to-toner ratio.

The bag fits the e-STUDIO 2006, 2007, 2303, 2306, 2307, 2309, 2505, 2505F, 2505H, 2506, 2507, 2802, 2809 and 2829 chassis. Toshiba rates one fill at approximately 55,000 pages under standard coverage. Treat the material as a service consumable rather than a customer-replaceable cartridge. Store the foil bag sealed and flat until the service visit.
