Primary and Transfer Charge Rollers

Charge rollers are critical for long lasting, high quality printouts in laser printers and copiers. KB Roller Tech’s special compounds enable charge rollers to maintain continuously stable electrical properties. Primary charge rollers are mostly soft coated rollers with sensitive surfaces and precisely defined electrical properties. They are in contact with the photoconductor and transfer electrical charge in the nip area. The contact arc is created by the soft charge roller touching the hard coated photo-conductor drum. KB RollerTech`s capabilities: Length: < 354 mm Hardness: 45 - 72 Asker C Electrical properties: 1 ~ 10M Ohm (bei 500V/20°C ± 5)
