Patent JP-H02129655-A (JP)
Title: Developing method
Inventor: GOTODA KATSUHIKO
IPC: G03G13/08
Filed: 1988-11-08
Abstract: PURPOSE:To prevent the ground of an image from being stained by making the absolute value of the potential of DC pulses applied to a developing roll small than the absolute value of the surface potential of a photosensitive body by a main corona discharge and larger than the absolute value of the surface potential of the photosensitive body irradiated with light after exposure. CONSTITUTION:The developing roll 4 is applied with the DC pulses and the potential of the DC pulses is smaller than the absolute value of the surface potential of the photosensitive body 1 by the main corona discharger 2 and larger than the absolute value of the surface potential of the photosensitive body 1 irradiated with light after exposure. Therefore, a developer which is charged electrostatically to the same polarity with the potential applied to the developing roll is possible transferred from the developing roll to the photosensitive body side, but never attracted from the photosensitive body 1 back to the developing roll 4. Consequently, a sharp image is obtained without such an state that the image becomes thin or has its stained ground.
