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： 图像形成设备（11）包括用于去除感光膜（12）上的残余电荷的电荷去除装置（20）。 从电荷移除装置的光源发射的光从对应于光敏膜（12）的光吸收特性中的最大吸收的一半的波长之间的范围中选择。 由于由电荷移除装置发射的光不会发生载流子产生，所以感光膜的充电能力和电荷保持能力得到改善，并且图像质量显着提高。
