摘要： An image forming apparatus (11) includes a charge removing device (20) for removing the residual charge on a photosensitive film (12). The light emitted from an optical source of the charge removing device is selected from the range between the wavelengths which correspond to half of the maximum absorbance in a light absorbance characteristic of the photosensitive film (12). Since carrier generation does not occur by the light emitted by the charge removing device, the charging ability and the charge retaining ability of the photosensitive film are improved, and the image quality is significantly improved.
摘要翻译：图像形成装置包括用于去除感光膜上的残留电荷的电荷去除装置。从电荷去除装置的光源发射的光从相应于感光膜的吸光度特性中最大吸光度的一半的波长之间的范围中选择。由于由电荷去除装置发出的光不会发生载流子的产生，所以提高了感光膜的充电能力和电荷保持能力，并且显着提高了图像质量。
