CHARGING MEMBER CONTAMINATION DETERMINING DEVICE |
| 摘要 |
Provided is a charging member contamination determining device including plural units that includes a charging member, a member to be charged and a measuring section that measures a discharging current value between the charging member and the member to be charged, a calculating section that calculates a difference between current values measured by two units among the plural units, and a determining section that determines the presence or absence of contamination in the charging member based on the difference between the current values for each combination of two units calculated by the calculating section. |
