A charge transport material (m1) comprising two fluorenylidene groups linked via a conjugated hydrazone linking group is new. A charge transport material (m1) of formula Y=N-N=X=N-N=Y' (I) is new. Y,Y' : 9-fluorenylidene group; X : conjugated linking group that allows the delocalization of pi electrons over at least Y and Y'. Independent claims are included for the following: (1) an organophotoreceptor (R1) comprising an electrically conductive substrate (s1) and a photoconductive element (e1) on (s1), where (e1) comprises (m1) and a charge generating compound (c1); (2) an electrophotographic imaging apparatus (A1) comprising a light imaging component and (R1) to receive light from the imaging component; and (3) an electrophotographic imaging process involving applying an electrical charge to a surface of (R1), imagewise exposing the surface of (R1) to radiation to dissipate charge in selected areas and to form a pattern of charged and uncharged areas on the surface, contacting the surface to a toner to create a toned image and transferring the toned image to substrate.
