NOVELTY - Amine compounds (I) are new.    USE - (I) are useful in: an electrophotographic photoconductor which is used in an image forming apparatus (all claimed) and a process cartridge; and an electronic device in an electronics field including solar cells and optical discs.    ADVANTAGE - (I): provide the electrophotographic photoconductor which stably provides a high- quality image by having high durability in long-term repeated use and by suppressing image density decrease or image degradation due to occurrence of image blurring, does not require any replacement, provides a high-resolution image, enables high-speed printing or apparatus downsizing due to reduction in photoconductor diameter, exhibits extremely superior effects; and are environmental resistances to repeated use.    DETAILED DESCRIPTION - Amine compounds of formula ((R1a-N(R2a)-CH2)n-Ar3a-N(Ar2a-(CH2-N(R2a)-R1a)m))-Ar1a-CH2-N(R2a)-R1a) (I) are new.    R1a, R2a = alkyl, aralkyl or aromatic hydrocarbyl (all optionally substituted); either    Ar1a = aromatic hydrocarbyl (optionally substituted);    Ar2a, Ar3a = alkyl, aralkyl or aromatic hydrocarbyl (all optionally substituted); or    Ar1aAr2a or Ar2aAr3a = heterocyclyl including N (optionally substituted); and    m, n = 0 or 1.    INDEPENDENT CLAIMS are also included for:    (1) an electrophotographic photoconductor comprising an electrically conductive substrate (31), and a photoconductive layer on the electrically conductive substrate, where the photoconductive layer includes (I); and    (2) an image forming apparatus comprising the electrophotographic photoconductor, a charging unit which charges a surface of the electrophotographic photoconductor, an exposure unit which exposes the charged surface of the electrophotographic photoconductor to form an electrostatic latent image, a developing unit which develops the electrostatic latent image using a toner to form a visible image, and a transfer unit which transfers the visible image to a recording medium.    DESCRIPTION OF DRAWING(S) - The figure shows a cross-sectional view of the electrophotographic photoconductor.
