Method of controlling an image forming apparatus when an emergency stop signal is generated
First Claim
1. A method of controlling an image forming apparatus which employs a two-component developing system in which toner is charged with the same polarity as a charging polarity of a photoreceptor, and in which apparatus a charging voltage and a developing bias voltage are applied after said photoreceptor is driven, comprising the steps of:
- stopping drive of said photoreceptor and application of the charging voltage and the developing bias voltage when an emergency stop signal is generated; and
raising the developing bias voltage before starting the drive of said photoreceptor, when said image forming apparatus is restarted.
