Zusammenfassung: | The present disclosure provides a charging member for electrophotographic equipment capable of providing constant and excellent uniform chargeability over a long period of time from low-temperature and low-humidity through high-temperature and high-humidity environments, while suppressing bleeding. A charging member for electrophotographic equipment includes an elastic layer and a surface layer formed around the elastic layer. The elastic layer includes the following (a) through (c): (a) an ion conducting agent that is solid at room temperature; (b) an ion conducting agent that is liquid at room temperature; and (c) an electron conducting agent with an average grain diameter of 25 to 90 nm and a DBP absorption of 152 ml/100 g or below. |
