Document Type and Number:
Japanese Patent JP7092033
Kind Code:
B2
Abstract:
An electrophotographic photoreceptor that includes a conductive support; and at least a charge generation layer and a charge transport layer on the conductive support, where the charge transport layer includes at least two layers of a first charge transport layer which is an outermost layer and a second charge transport layer which is in contact with the first charge transport layer, such that the elastic deformation ratio of a binder resin A contained in the first charge transport layer is T1(%) and the elastic deformation ratio of a binder resin B contained in the second charge transport layer is T2(%) such that T1 and T2 satisfy a relationship of {0≤(T1−T2)≤4}, the first charge transport layer contains a charge transport material α having a molecular weight of 600 or more, and the binder resin A and the binder resin B have different monomer units from each other.
