Abstract
This invention uses a toner which has |x|≧60, wherein a blow-off charge level is defined as x[μc/g], or a toner which has 11.0≦log ρ, wherein a volume intrinsic electric resistivity is defined as ρ[μc/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.
