The hydrogenated amorphous silicon (a-Si:H) photoreceptor used in printing systems produces image blurring at high temperature and humidity. We have examined the problem using infrared reflective-absorption spectroscopy (IR-RAS). We exposed a hydrogenated amorphous silicon carbide (a-SiC:H) film to a corona discharge at 35℃ and 80% RH. Adsorption and oxidation species on the film can be detected and determined by IR-RAS. NO^-_3, CO^<2->_3, Si-OH, H-OH, and Si-O-Si are detectable in the a-SiC:H film. The amount of them increases with corona exposure time. We clarify that these specids in a-SiC:H film cause the contact angles to decrease with the corona exposure time and blur the image.
