摘要： In the invention, oxidation-treated carbon black having good dispersibility is used to obtain a conductive brush having a uniform resistance even when it is finely processed. An image forming process is carried out by using the conductive brush, whereby abnormal discharge to a photoreceptor is suppressed, and an image defect due to charging unevenness is prevented from occurring without damaging the photoreceptor, so as to improve image quality. The photoreceptor is scraped uniformly and smoothly to prevent filming from occurring, whereby the maintenance property is improved.
