    摘要： An image forming apparatus which is capable of eliminating density irregularities of an image formed caused by potential irregularities of the photosensitive member when the drum is irradiated by a beam of constant luminous intensity. A laser driver irradiates a beam modulated based on an image signal onto a photosensitive member. A current controller variably controls a driving current for driving the laser driver. A PWM pulse width converter modulates a pulse width of the beam based on the image signal. A potential sensor measures the potential of the photosensitive member after the photosensitive member is irradiated by a beam having a predetermined luminous intensity. A selector causes the current controller to correct the driving current based on low frequency components of irregularities of the potential and changes a modulation coefficient used for modulating the pulse width based on high frequency components of the irregularities of the potential.

    摘要： An image forming apparatus that can provide a quality image in a stable manner without lowering the productivity. A reference image forming unit forms reference images on a transfer member. A plurality of sensing units detect densities of the formed reference images. A control unit adjusts respective output values from the plurality of sensing units according to a difference between the output values from the plurality of sensing units. The control unit performs error processing according to the difference between the output values from the plurality of sensing units when the control unit adjusts the output values from the plurality of sensing units.
