摘要： When a number of print pages, a driving time or a toner adhering amount exceeds a cleaning trigger value during no transfer operation, a circumferential speed of a secondary transfer roller is changed with respect to a circumferential speed of an intermediate transfer belt so as to clean the secondary transfer roller. Particularly, a surface of the secondary transfer roller is totally cleaned when the circumferential speed of the secondary transfer roller is made relatively faster and then slower or vice versa than the circumferential speed of the intermediate transfer belt because the surface of the secondary transfer roller is elastically deformed in both upstream and downstream directions so that the residual toner on the uneven foam surface of the secondary transfer roller is extruded.

摘要： A first roll brush is formed from material having the positive triboelectric charge polarity against toner. A positive bias is applied to the first roll brush through a first collection roller by a first bias application device. A second roll brush is formed from material having the negative triboelectric charge polarity against toner. A negative bias is applied to the second roll brush through a second collection roller by a second bias application device. Thus, the first and second roll brushes are applied by each of biases having polarity identical to the triboelectric charge polarity of material of the roll brush against toner. This enhances cleaning performance of both the roll brushes and prevents degradation of the cleaning performance.

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.
