摘要： When a developing agent prepared to have a preset toner density is loaded in a developing unit, a comparing reference level for controlling the toner density in the developing agent is changed to a value higher than the preset value in the initial stage of operation and fresh toner is supplied to the developing agent so that the toner density of the developing agent is increased in comparison to the reference level. Thereby, the developed density is prevented from decreasing due to an excess amount of friction charge of the toner.
摘要翻译：当准备好具有预设调色剂浓度的显影剂加载到显影单元中时，用于控制显影剂中的调色剂浓度的比较参考水平在初始操作阶段被改变为高于预设值的值，并且新鲜调色剂被提供给显影剂，使得与参考水平相比显影剂的调色剂浓度增加。由此，由于调色剂的摩擦带电量过大，阻止显影浓度的降低。
