Title:
画像形成装置の帯電工程評価方法
Document Type and Number:
Japanese Patent JP5157097
Kind Code:
B2
Abstract:
In an image forming apparatus, a photoconductor and a charge roller are in contact with each other and configured to rotate together at linear velocity v (millimeters/second). In this structure, a DC voltage is applied to the photoconductor and the charge roller while they are not rotating. In this state, parameters such as voltage, linear velocity, pressure contact force between the photoconductor and the charge roller are selected so that the ratio w/v (seconds), where w is the interval between two discharge marks occurring on surface of photoconductor, is between 0.005 to 0.035.
