Abstract
An electrophotographic photoconductor comprises an electroconductive substrate and a photoconductive layer formed thereon comprising as an effective component at least one pyrenylamine derivative of formula (I): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, W, j, k, l, m and n are specifically defined in the specification. Furthermore, a novel pyrenylamine derivative for use in the above electrophotographic photoconductor, an aldehyde compound, which is an intermediate for producing the pyrenylamine derivative, and methods of preparing the pyrenylamine derivative and the aldehyde compound are disclosed.
