An electrophotographic photoconductor includes an electroconductive support and a photoconductive layer formed thereon containing a diamine compound represented by formula (I): ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 each is independently a substituted or unsubstituted alkyl group or aryl group; R.sup.4 is hydrogen, an alkyl group or an alkoxyl group; n is an integer of 1 to 3; and ##STR2## is a substituted or unsubstituted bivalent arylene group or a bivalent heterocyclic group. This diamine compound is useful as a photoconductive material for electrophotographic photoconductors.
一种电子照相感光鼓包括一个电导支撑和在其上形成的一层光电导层,该光电导层包含一个由式(I)表示的二胺化合物:##STR1## 其中,R1、R2和R3各自独立地是取代或未取代的烷基或芳基;R4是氢、烷基或烷氧基;n是1到3的整数;而##STR2##是取代或未取代的双价芳基基团或双价杂环基团。这种二胺化合物可作为电子照相感光鼓的光电导材料使用。
