Examples of refreshing a photoconductive layer in an image forming apparatus are described. In one example, a method comprises performing a first refreshing cycle comprising applying, at a first refresh unit, a first refresh voltage to the photoconductive layer and applying, at a second refresh unit, a second refresh voltage to the photoconductive layer. A second refreshing cycle is performed comprising applying, at the first refresh unit, a third refresh voltage to the photoconductive layer, the third refresh voltage being higher than the first refresh voltage and higher than the second refresh voltage. Each of the first and second refreshing cycles electrically bias the photoconductive layer to a refresh polarity opposite to a print polarity applied during a print routine of the image forming apparatus.
