Problems solved by technology

As a result, the durability of the toner decreases, which can change the properties of the toner
In addition, fast printing is hindered because it takes time to form a toner layer with an appropriate thickness on the developing roller in the next developing process

Abstract

Provided is an image forming device performing hybrid development that uses magnetic carriers and nonmagnetic carriers. An electrical potential of a non-image portion on an image holder and an electrical potential of a direct current component of a developing bias voltage applied to a developing roller are determined so that a difference between the electrical potentials are less than or equal to a value at which a developing rate of the non-image portion is saturated.

Description

[0001] This application has priority to Korean Patent Application No. 10-2005-0028072 filed on April 4, 2005 and Korean Patent Application No. 10-2005-0098076 filed on October 18, 2005 in the Korean Intellectual Property Office. The descriptions of these patent applications are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to an electrophotographic image forming apparatus and a developing method performed by the electrophotographic image forming apparatus. More specifically, the present invention relates to an electrophotographic image forming apparatus using a magnetic carrier and a nonmagnetic carrier, and a developing method performed by the electrophotographic image forming apparatus. Background technique [0003] Examples of image development used in an image forming apparatus using electrophotography include two-component development, single-component development, and hybrid development. Two-component develo...
