Abstract
First and second dielectric portions and colored particles have −polarity, and a regulating portion and an externally added particles have +polarity. In a triboelectric series,(−)<second dielectric portion<first dielectric portion<regulating portion (+) and (−) colored particles<second dielectric portion<first dielectric portion<externally added particles (+). With work functions, the difference between the colored particles and the second dielectric portion<the difference between the second dielectric portion and the externally added particles, the difference between the colored particles and the first dielectric portion<the difference between the first dielectric portion and the externally added particles, and the difference between the colored particles and the regulating portion>the difference between the regulating portion and the externally added particles.
