Patent number: 5778286Abstract: An image forming apparatus adopting a non-magnetic one component developing system is arranged such that a charge brush and a developing roller are aligned along the circumference of a photoreceptor drum, that is rotatably driven, in order from an upstream side in a rotating direction of the photoreceptor drum. A transfer roller is placed opposing the photoreceptor drum with a sheet transportation path in-between. The charge brush, the developing roller and the transfer roller are rotatably driven while contacting the photoreceptor drum respectively. A photoconductive layer of the photoreceptor drum is made of an organic photoconductive material, and a coefficient of friction of the photoreceptor drum and the developing roller is selected to be not more than 0.5. As this eliminates the irregularity in rotary movement of the photoreceptor, offers a quality image and reduces a driving force for the photoreceptor drum, an apparatus of a light weight and high cost can be achieved.Type: GrantFiled: September 4, 1997Date of Patent: July 7, 1998Inventors: Eiichi Kido, Yuhi Yui, Toyokazu Mori, Mamoru Nozomi

Patent number: 5457521Abstract: An object of the invention is to prevent a silicone gas generated in a fixing unit from entering into a charger. A corona wind rises when the charger corona-discharges, and air is taken in through an outside-air intake. The air flows in through the air passage and the air inlet and flows out through a front opening as an air flow. The silicone gas is isolated by the airflow and prevented from entering into the charger.Type: GrantFiled: April 12, 1994Date of Patent: October 10, 1995Assignee: Sharp Kabushiki KaishaInventors: Takashi Makiura, Shinichi Azumi, Hiroaki Yoshida, Toyokazu Mori, Yoshinobu Tateishi, Mitsuyoshi Terada
