| 摘要 | A cleaning blade includes a polyurethane member that contains a polyurethane, the polyurethane member constituting at least a contact portion that comes in contact with a member to be cleaned. An infrared absorption spectrum obtained by infrared spectroscopy of the polyurethane member has a peak intensity ratio (A/B) of about 1.1 or more, where A represents an intensity of a spectral peak due to a carbonyl group that does not form a hydrogen bond, the spectral peak appearing in a range of about 1,730 cm−1 or more and about 1,740 cm−1 or less, and B represents an intensity of a spectral peak due to a carbonyl group that forms a hydrogen bond, the spectral peak appearing in a range of about 1,670 cm−1 or more and about 1,720 cm−1 or less. | ||
