Abstract: Disclosed is a printed circuit board comprising a contact terminal, which prevents a poor contact and reduces a manufacturing cost, and an image forming apparatus having the same. The printed circuit board comprises a circuit part for controlling and processing an operation of electronic appliance, and a large-area contact terminal formed by a group of small-area terminals for electric connection with external device. The small-area terminals can be formed in various types, respectively having regular size and shape and being distanced a predetermined interval. Accordingly, unevenness of the large-area contact terminal surface caused by soldering is prevented since a plurality of small-area terminals constitute a unit contact terminal of over a predetermined size. Therefore, quality of contact with external terminal improves. Further, manufacturing cost is reduced, and the manufacturing process becomes simple.

Abstract: A method of compensating for image quality controls a toner reproduction curve (TRC). The toner reproduction curve TRC &PHgr;(k) measured by a color toner density sensor is compared with a target TRC &PHgr;R to obtain a deviation &Dgr;&PHgr;. A variation &Dgr;VB of a developer bias VB is calculated from a Jacobian matrix (JB) of a measured developer bias VB to calculate a new developer bias VBN and determining a measured grid voltage VG as a new grid voltage VGN if the deviation (&Dgr;&PHgr;) is greater than a tolerance &Dgr;&PHgr;T. A backplating vector VBP is obtained from the grid voltage VGN and the developer bias VBN. The backplating vector VBP is compared with a critical value VT to set control parameters VGN and VBN and control the TRC &PHgr;. Thus, noise effects on the image quality are minimized to provide an output image closest to an input image quality so as to improve the image quality.
