The invention relates to a mono-layer type electronic photographic photoreceptor and an image forming device comprising the same. For the mono-layer type electronic photographic photoreceptor, a hole transport agent is the hydrazone compound shown in the following general formula (1), and an electron transport agent has a value within a range of 27-50 wt.% as solubility (measured temperature: 25 DEG C) in tetrahydrofuran. In the general formula (1), R<1> and R<2> are independent substituent groups of hydrogen atom, alkyl with 1-6 carbon atoms, alkoxyl group with 1-6 carbon atoms or dialkylamino; the alkyl in the dialkylamino contains 1-6 carbon atoms; R<3> and R<4> are independent substituent groups of alkyl with 1-6 carbon atoms, aralkyl group with 6-20 carbon atoms or aromatic group with 6-20 carbon atoms and m represents 0 or 1.
