Abstract

An image forming device has a developing process part comprising a plurality of developing process rollers, and a delivery part to move a printing paper to pass through the developing process part. The image forming device includes a skew sensor to detect a skew degree of the printing paper supplied to the developing process part by the delivery part, a potential forming part to form predetermined potential differences among the plurality of developing process rollers to make a developer be applied on the printing paper, and a controller to prevent the potential forming part from forming the predetermined potential differences on the plurality of process developing rollers when the skew degree of the printing paper deviates from a predetermined allowance range. Thus, the image forming device prevents an image from being formed when the skew degree of the printing paper deviates from the predetermined allowance range.

Description

technical field [0001] The present general inventive concept relates to an image forming apparatus and an image forming method, and more particularly, to an image forming apparatus and an image forming method that prevent printing if a printing paper is skewed. Background technique [0002] Conventionally, an image forming apparatus includes: a developing processing section having a plurality of developing processing rollers; and a paper feeding section for feeding printing paper to the developing processing section. The developing processing section selectively applies a developer to printing paper supplied from the paper supplying section, and forms an image on the printing paper. [0003] figure 1 is a schematic diagram illustrating skew of printing paper (P) in the conventional image forming apparatus 100 . As shown therein, a conventional image forming apparatus 100 includes a development processing section 130 and a paper supply section 140 . The paper feeding part ...
