摘要： An image forming apparatus is for transferring a toner image on an image carrier onto a transfer medium, and thermally fixing the toner image by a fixing device, and comprises a cleaner removing residual toner on the image carrier. The apparatus: acquires information relating to a distribution of a density of the residual toner at each position within a section on the image carrier at an end of an image forming job, the section extending from the transfer position to immediately before a cleaning position; determines, based on the information, whether or not the density of the residual toner at the transfer position exceeds a corresponding threshold density pertaining to occurrence of fusion of the residual toner; and causes, if determining negatively, the drive unit to stop when the image forming job is completed and the residual toner at the transfer position reaches a predetermined position within the section.

摘要： An image forming apparatus having: a toner image carrier; a transfer member; a transfer voltage applying device which applies a bias voltage to the transfer member; a voltage controller which performs constant voltage control on the transfer voltage applying device; a transfer contribution current detecting device; an antistatic member for removing static electricity from the record medium after transfer of a toner image; and an antistatic voltage applying device which applies an AC voltage to the antistatic member. The transfer contribution current detecting device measures current values during a current detection time, which corresponds to an integral multiple of a period of the AC voltage applied to the antistatic member, and detects a transfer contribution current value from the measured values, and the voltage controller controls the bias voltage applied to the transfer member based on the transfer contribution current value.

摘要： Brush rollers rotate in a direction indicated by an arrow while being in contact with an image formation surface to remove toner remaining on the image formation surface from an intermediate transfer belt. The brush rollers each mainly include a rotational shaft and a brush. The brush rollers face the intermediate transfer belt with brush winding directions being opposite from one another. The brush rollers rotate in the direction indicated by the arrow. Thus, seams of the brush rollers can be prevented from being in contact with the same portion on the image formation surface of the intermediate transfer belt.
