A protective layer setting unit includes a protective agent and an application unit configured to apply the protective agent to an image carrying member in a manner sufficient to satisfy equations (1) and (2). A surface condition of the image carrying member is determined by an applied-agent amount index “X” and an agent coating ratio “Y,” and a ratio of “X/Y” is set to 0.020 or less after applying the protective agent for 120 minutes. applied-agent amount index X=Sb/Sa (1) agent coating ratio Y=(A0−A)/A0×100(%) (2)
摘要:
A protective layer setting unit includes a protective agent, and an application unit for applying the protective agent on an image carrying member. An attenuated total reflection (ATR) method is used for detecting a surface condition of the image carrying member after applying the protective agent. A peak Pa at a given wavenumber, attributed to the image carrying member, has a peak area Sa in an infrared spectrum observed after applying the protective agent. A peak Pb at a given wavenumber, attributed to the protective agent, has a peak area Sb in the infrared spectrum observed after applying the protective agent. A peak area ratio of Sb/Sa is used for evaluating the protective layer setting unit. The protective layer setting unit is accepted when the Sb/Sa is set to a given range after applying the protective agent to the image carrying member for a given time period.

An image forming apparatus includes a charger, a developing device, a cleaning device, a protective-agent bar, and a brush. The charger uniformly charges an image carrier. The developing device develops an electrostatic latent image formed on the image carrier to obtain a toner image as a visual image. The cleaning device removes toner remaining on the surface of the image carrier from which the toner image has been transferred onto a transfer material. The protective-agent bar contains a protective agent. The brush comes in contact with the protective-agent bar and the image carrier while rotating such that the protective agent adheres thereto and is supplied to the image carrier in an irregular form.
