PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductive resin composition for manufacturing a molded product with sufficiently small resistance irregularity, a molded product with sufficiently small resistance irregularity, a transfer belt for electrophotography, and an image forming device comprising the transfer belt. SOLUTION: The manufacturing method of the semiconductive resin composition containing a conductive substance, a polymer A with a relatively high dispersibility of the conductive substance, and a polymer B with a relatively low dispersibility of the conductive substance comprises a first kneading step of melting and kneading at least a conductive substance and a polymer A, and a polymer B by a ratio of 100 wt.% or less with respect to the polymer A using a batch type kneader; and a second kneading step of adding the polymer B to the kneaded product and further melting and kneading the same. The molded product has a structure, wherein the polymer A region with the conductive substance dispersed is dispersed in the polymer B region. Also, there is provided a transfer belt for electrophotography, and an image forming device comprising the transfer belt. COPYRIGHT: (C)2010,JPO&INPIT
