Abstract:
A developer including a colored resin particle and an external additive added to a surface of the colored resin particle and having a diameter smaller than or equal to 200 nm is provided. The external additive includes a nitrogen-containing resin particle. In elemental analysis of the nitrogen-containing resin particle, a peak appearing in a range of 0.38-0.42 keV is expressed as an N-peak, and a peak appearing in a range of 0.48-0.52 keV is expressed as an O-peak. Maximum count numbers in the N-peak and the O-peak of the external additive on a surface of the colored resin particle are respectively expressed as N1 and O1. Maximum count numbers in the N-peak and the O-peak of the surface of the colored resin particle where no external additive is observed are respectively expressed as N2 and O2. The count numbers N1, O1, N2 and O2 satisfy 1.7×(N2/O2)<(N1/O1).

Claim (Index 1):
A developer comprising:\n a colored resin particle; and an external additive added to a surface of the colored resin particle and having a diameter smaller than or equal to 200 [nm], the external additive comprising a nitrogen-containing resin particle, wherein, in elemental analysis of the nitrogen-containing resin particle, when a peak appearing in a range from 0.38 to 0.42 keV is expressed as an N-peak, a peak appearing in a range from 0.48 to 0.52 keV is expressed as an O-peak, a maximum count number in the N-peak and a maximum count number in the O-peak of the external additive on a surface of the colored resin particle are respectively expressed as N1 and O1, and a maximum count number in the N-peak and a maximum count number in the O-peak of the surface of the colored resin particle where no external additive is observed are respectively expressed as N2 and O2, the count numbers N1, O1, N2 and O2 satisfy 1.7\u00d7(N2/O2)<(N1/O1), and wherein the developer has a cohesion degree in a range from 63.7 to 80.9.
