Abstract
A controller takes in a detection signal indicating the surface electrical potential of a photoconductive drum () from a surface electrical potential sensor (step #), and determines whether the surface electrical potential is smaller than the predetermined threshold value (step #). As a result, when the controller () determines that the surface electrical potential is equal to or greater than the predetermined threshold value (NO in step #), it uses the low print rate density patch to execute the density adjustments in accordance with the toner density and the developing bias associated with the density patch (step #). When the controller () determines that the surface electrical potential is smaller than the predetermined threshold value (NO in step #), it uses a high print rate density patch to execute the density adjustments in accordance with the toner density and the developing bias associated with the density patch (step #).
