摘要： A process cartridge includes a protective agent, a photoconductor, a charging unit, a development unit, a cleaning unit, and an application unit. The protective agent includes paraffin as main component. The photoconductor has a surface including polycarbonate applied with the protective agent. The development unit develops a latent image on the photoconductor. The cleaning unit removes materials remaining on the photoconductor. The application unit applies the protective agent to the surface of photoconductor. One peak in a given binding energy range is used to determine a coating condition of the photoconductor coated by the agent. The coating condition is determined by comparing an area ratio A0 before applying the agent and an area ratio A after applying the agent, each of which is an area ratio with respect to a total area of C1s spectrum of the photoconductor. The coating ratio of the photoconductor is computed by (A0−A)/A0×100.

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.

摘要： 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.

摘要： A charge member that can reduce charge irregularities of a member to be charged caused by variations in the gap between the member to be charged and the charge member even when using a member to be charged (photosensitive member, and the like) that has circumferential fluctuations. The charge member which is arranged electrically without making contact with the member to be charged, and which charges the member to be charged by applying AC voltage superimposed on DC voltage, and which is formed of a rotatable roller, is arranged electrically without making contact with the member to be charged having circumferential fluctuations of 4 to 80 μm within the image formation area, and which has a plurality of stage differences with a height difference of 2 to 30 μm on the surface of the roller; and the stage differences in the area opposing the member to be charged are five to thirty in relation to a distance of 0.5 mm in the circumferential direction of the roller. Charging without charge irregularities is thereby possible.
