摘要： PROBLEM TO BE SOLVED: To stably maintain a transfer current within a reference range in real time even if transfer environment changes due to, for example, moisture absorption of paper.SOLUTION: The value of current passing through a secondary transfer section 14 is detected by an ammeter 33 via an electrode 11 located opposite to a secondary transfer roller 13. A variable resistor 35 is connected to a pre-transfer guide 20a for feeding paper P to the secondary transfer section 14. If the value detected by the ammeter 33 is outside a reference range, the value of current consumed for secondary transfer is kept within the reference range by adjusting the variable resistor 35, thereby changing a leak electrode flowing in the paper P. Since current in the secondary transfer section 14 is directly detected, a real-time performance is excellent. Also, since the need to change the output of a bias is eliminated, stability is excellent.
摘要翻译：要解决的问题：即使由于例如纸的吸湿引起的转印环境变化，也可以实时地将转印电流保持在基准范围内。解决方案：通过二次转印部分14的电流值通过电流计33通过与二次转印辊13相对的电极11来检测。可变电阻器35连接到用于进给的预转印导向件20a 纸张P到二次转印部分14.如果由电流表33检测到的值超出参考范围，则通过调节可变电阻器35将二次转印消耗的电流值保持在参考范围内，从而改变流过的电极由于直接检测到二次转印部14中的电流，所以实时性能优异。此外，由于消除了改变偏压输出的需要，因此稳定性优异。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus that satisfactorily transfers a toner image from a transfer belt to paper regardless of a resistance variation of a secondary transfer roller, a change in the durability of an electricity removal needle, and an environmental change.
SOLUTION: A transfer current flowing in the secondary transfer roller 13 is detected by a transfer current detection part 44A. An electricity removal current flowing in the electricity removal needle 47 is detected by an electricity removal current detection part 44B. A voltage control part 45A controls a bias voltage applied to the secondary transfer roller 11 so that a transfer contribution current falls within a specific range. The transfer contribution current is a value obtained by removing the electricity removal current detected by the electricity removal current detection part 44B, from the transfer current detected by the transfer current detection part 44A.
