1. An image-quality stabilizer for an electrophotographic apparatus comprising electrophotographic processing means, said electrophotographic processing means including a photoreceptor and transfer means, said image-quality stabilizer comprising:

  • optical detecting means for optically detecting an amount of toner deposited on said photoreceptor;

    process control means for controlling said electrophotographic processing means so that an amount of toner forming a reference toner image on said photoreceptor is equal to a predetermined reference value;

    transfer control means for controlling said transfer means so as to transfer a reference toner image formed after controlling said electrophotographic processing means to a transfer sheet; and

    reference-value adjusting means for adjusting the reference value based on a value detected by said optical detecting means after transferring the reference toner image to the transfer sheet.
