Abstract
Official abstract text for this publication.
An intermediate transfer belt for use in electrophotography is provided. The intermediate transfer belt includes a thermoplastic resin having a vinylidene difluoride (VdF) structure. The intermediate transfer belt has a degree of crystallinity in the range of 17% to 39%.
First claim
Opening claim text (preview).
What is claimed is: 1 . An intermediate transfer belt for use in electrophotography, comprising: a thermoplastic resin having a vinylidene difluoride (VdF) structure, wherein the intermediate transfer belt has a degree of crystallinity in the range of 17% to 39%. 2 . The intermediate transfer belt according to claim 1 , wherein the thermoplastic resin includes polyvinylidene difluoride (PVdF). 3 . The intermediate transfer belt according to claim 1 , wherein the thermoplastic resin includes a copolymer of vinylidene difluoride (VdF) and hexafluoropropylene (HFP). 4 . The intermediate transfer belt according to claim 1 , wherein, when the intermediate transfer belt is subjected to a thermal analysis with a differential scanning calorimeter, a peak originated from heat of crystal melting is observed in each temperature range of 130° C. to 138° C., 155° C. to 160° C., and 165° C. to 172° C., and the following in equations are satisfied: 0.15≦Δ H 1/Δ H 3≦0.92 0.41≦Δ H 2/Δ H 3≦0.99 wherein ΔH1, ΔH2, and ΔH3 represent amounts of heat of crystal melting in each temperature range of 130° C. to 138° C., 155° C. to 160° C., and 165° C. to 172° C., respectively. 5 . The intermediate transfer belt according to claim 1 , wherein the intermediate transfer belt has a glossiness of 50 or more when the glossiness is measured at incident and light-receiving angles of 20 degrees. 6 . The intermediate transfer belt according to claim 1 , wherein the intermediate transfer belt has a thickness in the range of 100 to 200 μm. 7 . The intermediate transfer belt according to claim 1 , wherein the number of times of folding endurance of the intermediate transfer belt is 20,000 times or more when measured under a load of 9.8 N by an MIT folding endurance test.
