Document Type and Number:
Japanese Patent JP2002296908
Kind Code:
A
Abstract:
To realize image formation with small roughness without making a device complicated.
In the device, the maximum value of D is made to be ≥3 when D={Br×(dBr/dr)+Bθ×(dBθ/dr)} is calculated, when D is obtained from magnetic flux on a developing sleeve in a range satisfying tan-1 (Br/Bθ)>π/4 by developing pole.
