Electrostatic image forming device with conditional toner cleaning roller

   
   

In a laser printer, when a sheet of paper, which is to be supplied in between a photosensitive drum and a transfer roller, is jammed, after the sheet of paper is removed and the jam is cleared up, a developing jam control program is executed to rotate a drum cleaning roller at a rotational speed higher than a normal rotational speed and to apply the transfer roller with a reverse bias voltage whose polarity is the same as that of the charged toner.

En una impresora laser, cuando una hoja del papel, que debe ser provisto entre un tambor fotosensible y un rodillo de la transferencia, se atora, después de que la hoja del papel se quite y es el atasco despejó para arriba, un programa de control del atasco que se convierte se ejecuta para rotar un rodillo de la limpieza de tambor a una velocidad rotatoria más arriba que una velocidad rotatoria normal y para aplicar el rodillo de la transferencia con un voltaje de polarización reversa que polaridad sea igual que la del toner cargado.
