    摘要： A fixing apparatus has first and second heating members and a current control unit which controls a number of waves and each of a first AC current to the first heating member and a second AC current to the second heating member in a positive-negative symmetrical pattern by a unit of predetermined number of half-waves. Regardless of a duty ratio of the first heating member and the second heating member, when the current control unit controls a number of waves so that the second AC current is larger than the first AC current in the first duty ratio, the current control unit controls the number of waves so that the first AC current is larger than the second AC current in a second duty ratio adjacent to the first duty ratio.

    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.
