摘要： In an image forming apparatus a primary transfer is carried out such that toner images on a plurality of photoreceptors are transferred and laminated onto an intermediate transfer member, and a recording paper and the intermediate transfer member are sandwiched between a secondary transfer roller disposed so as to be in contact with the intermediate transfer member and a secondary transfer counter roller disposed opposite to the secondary transfer roller, to carry out a secondary transfer that the toner images on the intermediate transfer member are transferred onto the recording paper. At the time, an electric field is applied to the recording paper, and further the secondary transfer counter roller is switched by a switch between grounded state and floating state so that a potential difference between the intermediate transfer member and the secondary transfer roller can be adjusted.

摘要： A method of measuring a resistance of a transfer roller. The method includes driving a transfer belt supported by plural rollers and disposed in a transfer unit, which transfers an image from a photoconductive medium onto a recording medium, and calculating the resistance of the transfer belt while rotating the transfer belt at least one revolution. Accordingly, a testing voltage is prevented from continually being applied to an identical area of the transfer belt, thus preventing deformation and abrasions of the transfer belt due to stress. Also, an accurate average resistance to apply a compensated voltage can be measured according to an environment, thus facilitating the supply of a uniform amount of an electric current to the transfer roller and the formation of a high-resolution image.

摘要： An apparatus and method of driving a transfer belt are disclosed. The apparatus and method comprise driving the transfer belt provided in an image forming apparatus by a predetermined distance when the transfer belt has been stopped for a predetermined time, and thus varying the contact portion with a plurality of rollers provided on the transfer belt. Image contamination due to deformation on the belt can be avoided. Additionally, because the rotation time of the driving source can be set to a predetermined time during the power-saving mode, power consumption can be minimized.
