Title:
IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3180995
Kind Code:
B2
Abstract:
PURPOSE: To form a clear image by applying an intermittent vibration field based on DC offset voltage to a development bias voltage generating means and applying a specified DC field thereto during non-vibration periods in the field.
CONSTITUTION: An LED unit 2 in a photosensitive drum 1 is held by a head block 24 and its exposure position is deflected slightly to the downstream side in the rotating direction from the nearest drum/sleeve contact point so as to form an image on the photoconductive layer 1c of the photoreceptor drum 1. A development bias voltage generating means is connected to a development sleeve 30 so as to allow the application of an intermittent vibration field having repetitive vibration periods and non-vibration periods. The development bias voltage generating means receives application of the intermittent vibration field including a vibration field based on DC offset voltage and receives application of a DC field which has a relationship &verbar Va&verbar >&verbar Vo&verbar during the non-vibration periods in the intermittent vibration field, where Va expresses an average value of the applied development bias voltage and Vo expresses DC offset voltage.
