Title: Developing device and image forming device
Inventor: OKANO KEIJI
IPC: G03G15/06
Filed: 2000-12-11
Abstract: PROBLEM TO BE SOLVED: To obtain a developing device capable of suppressing surface fogging on a high density especially, and made excellent in dot reproducibility by improving developing bias applied at the time of developing. SOLUTION: By changing the ratio (treated as the form of a duty ratio) of the duration Ta of fly voltage Vmax to the duration Tb of return voltage Vmin with respect to the developing bias obtained by superposing DC voltage on AC voltage and applied at the time of developing, the mean value of time Vdc varies. Thus, developing density is adjusted by increasing developing contrast. By setting a density value from a low density to the high density such as D1→D-2→D-3 (standard value)→D-4→D-5, the duty ratio (a) becomes higher in the order of D1→D5 so as to make Vdc high, and frequency (f) is made high on the high density sides D-4 and D-5. For example, in the case of Vpp=1400 V, Vmax=-1300 V and Vmin=-100 V, duty ratio (a) and frequency (f) is as follows respectively, D-3: a=35.7%, f=2000 Hz, D-5: a=42.9% and f=2400 Hz.
