    摘要: An image forming apparatus includes an image bearer to bear a latent image, a charging device to charge the image bearer, a developing device to develop the latent image on the image bearer, a cleaning device to clean a surface of the image bearer, a target component including at least one of the image bearer, the charging device, the developing device, and the cleaning device, and a temperature change suppression member opposed adjacent to or disposed in contact with an outer peripheral face of the target component. The temperature change suppression member suppresses a temperature change of the target component.

    摘要: An image forming apparatus includes a latent image bearer, an intermediate transferor, a primary transferor, a second transferor, and a cleaning blade. The latent image bearer has a surface onto which a lubricant comprising zinc stearate is supplied. The intermediate transferor has a surface onto which the toner image is transferred, the surface including an adhering region to which the lubricant from the latent image bearer adheres. The cleaning blade cleans the surface of the intermediate transferor including the adhering region, after the toner image is secondarily transferred. In a region outside at least a horizontal A4 sheet passing width on the intermediate transferor, a ratio of a peak area derived from zinc stearate to a peak area derived from the intermediate transferor in a difference spectrum between attenuated total reflection (ATR) infrared absorption spectrums of the intermediate transferor in an unused state and after use is 0.892 or less.
