DEVELOPING DEVICE FOR ONE-COMPONENT DEVELOPMENT

摘要

PURPOSE:To provide a developing device for one-component development capable of stabilizing the electrification of a toner and obtaining a high-quality, noiseless, and stable image. CONSTITUTION:When a developing blade 9 is brought into contact with both a development roller 4 and a toner feed roller 5, the toner 6 fed from a toner feed member 3 is prevented from flowing directly to the development roller 4. The electrification of the toner 6 is stabilized due to the two-stage preliminary electrification process.
