    • An image forming apparatus and a control method thereof to improve quality of an image in consideration of a change in posture of a print media. The image forming apparatus can include a transferred unit on which a visible image is formed, a transferring unit to form a transfer region through which the visible image is transferred onto a print medium, along with the transferred unit, a bias supplying unit to supply bias to the transferring unit so that a transfer electric field is produced in the transfer region, and a controller to control the bias supplying unit to supply different first to third biases to the transferring unit while at least first to third regions of the print medium pass through the transfer region, respectively.
    • 考虑到打印介质的姿势变化的图像形成装置及其控制方法来提高图像的质量。 图像形成装置可以包括其上形成有可见图像的转印单元,转印单元,用于形成转印区域,通过该转印区域将可见图像与转印单元一起转印到打印介质上,偏压供应单元提供偏置 转印单元,使得在转印区域中产生转印电场,以及控制器,用于控制偏压供应单元,以在打印介质的至少第一至第三区域通过时向转印单元提供不同的第一至第三偏压 转移区域。
