Patent Number: 6,165,665

Title: Electrophotographic imaging apparatus and toner

Abstract: This invention uses a toner which has .vertline.x.vertline..gtoreq.60, wherein a blow-off charge level is defined as x[.mu.c/g], or a toner which has 11.0.ltoreq.log .rho., wherein a volume intrinsic electric resistivity is defined as .rho.[.mu.c/g]. Alternatively, this invention uses a capsulated toner consisting of a core and a shell resin enclosing the outer of the core, characterized in that the shell resin does not comprise a charge control agent (CCA) for controlling a charge level, but the core only comprises said CCA.
