摘要:
A toner for the development of an electrostatic image is provided wherein at least one layer of a particulate resin is coated onto a substantial portion of the surface of an agglomerate of particles made from at least primary polymer particles and primary colorant particles, wherein at least one of the primary polymer particles and the particulate resin contains a wax, and the particulate resin of the outermost layer is substantially free of wax and a process for producing the toner.
摘要:
The present invention is directed to an electrostatic image-developing toner which is used for an electronograph and the like. The toner comprises at least core particles and fine particles being present on the surfaces of the core particles and has a mean particle size of 0.01-1 &mgr;m. The fine particles are polymer of a monomer and contain charge-controlling agent which is soluble in the monomer before polymerization.

摘要:
A photosensitive member for electrophotography having a photosensitive layer containing a hydrazone compound represented by the following general formula [I]: ##STR1## wherein R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom; R.sup.3 represents a halogen atom; m is 1 or 2; and n is 0, 1 or 2. The photosensitive member has not only extremely high sensitivity but also sufficiently low residual potential. It is also highly resistant to fatigue so that the repeated use provides it with little accumulation of residual potential and little variation of surface potential and sensitivity.
