摘要： A roller for use in a developing unit of an image forming apparatus may include a non-conductive shaft member and a non-conductive member to surround at least a part of an outer periphery of the shaft member. The shaft member may include a cylindrical rolling part and a pair of support parts formed to project from both ends of the rolling part in a lengthwise direction. The rolling part of the shaft member may be arranged opposite a charge roller in a developing unit and may rotate in contact with the charge roller to absorb and remove foreign substances adhered to a surface of the charge roller.

摘要： An image forming apparatus and method for controlling a charge of a toner are provided. The apparatus and method includes a toner supplying roller; a developing roller for supplying the toner to an organic photoconductor; a charge controller for adjusting the charge of the toner on the developing roller; a developing current detector for detecting a change in current for a developing voltage; and a charge controlling voltage controller for adjusting a charge controlling voltage according to the detection result. The apparatus can uniformly maintain the quality of an image by recognizing a change in the charge of toner based on a change in the environment. Also, the image forming apparatus indicates a proper toner replacement time by determining when the charge of the toner is abnormally low as a toner shortage state and displaying the toner shortage state on a panel operating unit.
