Title:
DEVELOPING METHOD
Document Type and Number:
Japanese Patent JP3363505
Kind Code:
B2
Abstract:

PURPOSE: To prevent the generation of fogging and tailing and thereby to enable a toner image with clear edge lines to be formed at the time of developing an electrostatic latent image by applying an oscillatory bias voltage to a developer carrier.
CONSTITUTION: A first peak voltage V1 of the oscillatory bias voltage V(t) applied to the developer carrier is at the level between an electrostatic latent image visualized part potential VL and an electrostatic latent image background part potential VD. A second peak voltage V2 is at the opposite position to the voltage level of the first peak voltage as to the visualized part potential VL.
