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： A test pattern P3 longer than a length Ld corresponding to a circumferential length of a developing roller is formed along a moving direction of a photosensitive member (or developing roller). The developing roller transports a great quantity of toner on its surface in a first revolution thereof and hence, the test pattern has a high density. When the residual toner runs low, the toner transport quantity is decreased in the subsequent revolution, so that the test pattern P3 is decreased in the density at its portion beyond the length Ld from its head. If a density difference is observed at place corresponding to a boundary between image portions formed in the first revolution and the second revolution, it is concluded that image quality is degraded due to the shortage of residual toner.
摘要翻译： 沿着感光构件（或显影辊）的移动方向形成长于对应于显影辊的圆周长度的长度Ld的测试图案P3。 显影辊在其第一圈中在其表面上输送大量调色剂，因此测试图案具有高密度。 当残留调色剂运行低时，调色剂输送量在随后的旋转中减小，使得测试图案P3在其头部的长度Ld以上的部分处的密度降低。 如果在与第一旋转形成的图像部分和第二旋转之间的边界对应的位置处观察到浓度差，则得出结论，由于残留调色剂不足，图像质量下降。
