Abstract:
An image forming apparatus includes a photosensitive member, a charging roller, an exposure device, a developing device, a transfer member, a fixing device, an outputting portion for outputting a recording material on which a toner image is fixed, a voltage source for output the charging voltage, a voltage setting portion for setting the charging voltage, an executing portion for executing an output process of a test chart including a plurality of adjusting images in setting of peak-to-peak voltage values of AC voltages at a plurality of different values, and an inputting portion through which an instruction of execution of the output process of the test chart is inputted.

Claim (Index 14):
An image forming apparatus according to  claim 1 , further comprising a setting portion configured to set the peak-to-peak voltage value, providing a predetermined target discharge current value, in a period other than an image forming portion, on the basis of a detection result of values of alternating currents flowing through said charging roller when said photosensitive member is charged by applying, to said charging roller, the charging voltages successively changed in peak-to-peak voltage to the plurality of different values while maintaining the DC voltage at a certain value,\n wherein said executing portion controls said voltage setting portion in the output process of the test chart so that the peak-to-peak voltage value when at least one of the adjusting images is formed is set at the peak-to-peak voltage value providing the predetermined target discharge current value set by said setting portion.
