Toner compositions and additives

A developer comprising:

• a toner composition;
• and a toner carrier, wherein the toner composition comprising:
• toner particles comprising at least one resin, an optional colorant, an optional wax, and a polymeric toner additive on at least a portion of an external surface of the toner particles, the polymeric toner additive comprising:
• a first polymeric resin comprising a cross-linked fluorinated acrylic monomer, a cross-linkable monomer comprising divinyl benzene at 30 wt % of the first polymeric resin, and a fluorinated divinyl crosslinking agent, wherein the first polymeric resin has an average or medium particle size (D50) of from about 20 nanometers to about 40 nanometers;
• a second polymeric resin comprising cyclohexylmethacrylate (CHMA), divinyl benzene at 25 wt % of the second polymeric resin, and a charge control agent comprising a nitrogen containing group at 0.1 wt % to 1.5 wt % of the second polymeric resin, wherein the second polymeric resin has an average or medium particle size (D50) of from about 71 nanometers to about 115 nanometers;
• and
• wherein the charge control agent comprises dipropylaminoethyl methacrylate, diisopropylaminoethyl methacrylate, dibutylaminoethyl methacrylate, or a combination thereof;
• and
• wherein the toner composition comprises no titania.
