An image forming device includes a photoconductor, a motor, a charging member, a cleaning blade, and an abnormality determining unit. The motor is configured to drive the photoconductor to rotate. The charging member is configured to charge the photoconductor. The cleaning blade is configured to contact the photoconductor and remove residual toner from a surface of the photoconductor. The abnormality determining unit is configured to determine abnormality of the cleaning blade based on a motor current flowing in the motor and a gap between the photoconductor and the charging member.
