Abstract:
1. An image forming apparatus comprising: an electrophotographic photoconductor having a conductive support and a photosensitive layer disposed on the conductive support and containing a charge generation substance and a charge transportation substance; charging means for charging the electrophotographic photoconductor; exposure means for forming electrostatic latent images by applying exposure corresponding to image information to the charged electrophotographic photoconductor; developing means containing toners, for developing the electrostatic latent images by supplying toners to the surface of the electrophotographic photoconductor thereby forming toner images; and transfer means for transferring the toner images from the surface of the electrophotographic photoconductor to a recording medium, wherein, the charge transportation substance contained in the photosensitive layer of the electrophotographic photoconductor contains an enamine compound represented by the following general formula (2), and a volume average particle diameter of the toners contained in the developing means is in a range from 4 μm to 7 μm wherein b, c and d each represent an optionally-substituted alkyl group, an optionally-substituted alkoxy group, an optionally-substituted dialkylamino group, an optionally-substituted aryl group, a halogen atom, or a hydrogen atom; i, k and j each indicate an integer of from 1 to 5; when i is 2 or more, then the “b”s may be the same or different and may bond to each other to form a cyclic structure; when k is 2 or more, then the “c”s may be the same or different and may bond to each other to form a cyclic structure; and when j is 2 or more, then the “d”s may be the same or different and may bond to each other to form a cyclic structure; Ar
