Abstract
A modified polyurethane carrier substrate is provided. The modified polyurethane carrier substrate is formed from a modified polyurethane. The modified polyurethane includes a soft segment and a hard segment. The soft segment is formed from a polyol. The hard segment is formed from diisocyanate and a chain extender. The chain extender is dianhydride. A common logarithm of a ratio of a storage modulus of the modified polyurethane carrier substrate at −30° C. to a storage modulus of the modified polyurethane carrier substrate at 150° C. ranges from 0.40 to 1.30.
