Two methods of surface treatment have been used to produce aluminum substrate which is called Mirror surface base material for organic photo conductor. One method is to atomize aluminum substrate on organic photo conductor directly and then carry on the anodic treatment which is called Anode surface base material. Therefore, the surface roughness was equal to the wave length of laser and the reflection light was eliminated by optical interference effect.

目前生产感光鼓所需的铝基材，其表面处理有两种做法，第一个做法就是直接在感光鼓的铝基材表面先进行雾化处理后再进行阳极处理，经阳极处理后的铝基材称为阳极基材，其粗造度Ra 值等於雷射光的波长，藉由光学干涉的原理将反射光消除。
