Abstract: Provided are an asymmetric butadiene-based charge transporting compound represented by one of Formula (1) and (1′) as in claim 1, an electrophotographic photoreceptor including the asymmetric butadiene-based charge transporting compound, and an electrophotographic imaging apparatus. The electrophotographic photoreceptor including the organic photoconductive material as a charge transporting material may not cause a problem, such as partial crystallization during film formation and may have a high charge potential, a sufficient photoresponsive property with high sensitivity, and a high durability. Moreover, these properties may be all maintained even in the case of exposure to light as well as use in low-temperature environments or high-speed processes, thus having high reliability.
