Embodiment Construction

[0036] Referring now in detail to the embodiments, examples of which are illustrated in the drawings, wherein like reference numerals refer to like elements throughout.

[0037] figure 1 is a view showing the image forming apparatus 100 according to the embodiment. specifically, figure 1 The image forming apparatus 100 is an electrophotographic type monochrome image forming apparatus for forming only monochrome images. Such as figure 1 The illustrated image forming apparatus 100 includes a housing 104 , a paper feeding unit 106 , a photoconductor 108 , a light scanning unit 110 , a developing cartridge 112 , a transfer roller 114 , and a fixing unit 116 .

[0038] The casing 104 forms the appearance of the image forming apparatus 100 . A paper feeding unit 106 is provided in the casing 104 . Paper 102 is located in a paper supply unit 106 .

[0039] The photoconductor 108 is formed in the form of a cylindrical drum extending a predetermined length corresponding to the wi...

Abstract

An image forming apparatus (100) and a method of controlling the same are provided. A plurality of cells (302) formed at the surface of a transfer roller (114) are filled with a developing agent (122) to initialize the transfer roller, thereby suppressing contamination and electrical non-uniformity of the transfer roller. A method of controlling an image forming apparatus includes determining whether a transfer roller mounted in the image forming apparatus is a new one and, upon determining that the transfer roller is a new one, feeding a developing agent to the surface of the transfer roller and filling a plurality of cells formed at the surface of the transfer roller with the developing agent to initialize the transfer roller.

Description

technical field [0001] Embodiments of the present invention relate to an image forming apparatus including a transfer roller for charging paper so as to attract a development agent to the paper, and a control method thereof. Background technique [0002] An electrophotographic type image forming apparatus feeds a toner image generated by a developing member to a recording medium (paper) using a transfer member. Corona mode and transfer roller mode are known transfer modes. In consideration of miniaturization of the image forming apparatus and ozone generation in the corona mode, the transfer roller mode is mainly used. [0003] In the transfer roller mode, a transfer bias is applied to a transfer member (ie, a transfer roller) to generate a transfer field, and transfer is electrostatically performed according to the transfer field. However, in the transfer roller mode, if the transfer roller contains dirt before the paper contacts the transfer roller, the transfer roller c...
