Abstract:
An electrostatic imaging device comprising:a photoreceptor drum for carrying thereon a toner layer having an electrostatic latent image;a transcription roller for transcribing said toner layer onto a recording sheet;a power source for providing a transcription voltage and transcription current to said transcription roller;a voltmeter for measuring said transcription voltage;an ammeter for measuring said transcription current; anda ROM for storing a first data for a first characteristic between said transcription voltage and transcription current and a second data for a plurality of second characteristics between said transcription voltage and said transcription current, said power source providing electrical power to said transcription roller based on said first characteristic during an initialization of said transcription roller, said power source selecting one of said second characteristics based on said transcription voltage and said transcription current measured during said initialization period, said power source providing power to said transcription roller during a normal operation of said transcription roller based on said selected one of said second characteristics.
