Abstract
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.
