An electrostatic latent image developing toner has positive chargeability and includes a plurality of toner particles. The toner particles each include primary domains made from a primary mixture. The primary mixture contains a wax and an antioxidant. The antioxidant is contained in an amount of at least 1.8 parts by mass and no greater than 15.8 parts by mass relative to 100 parts by mass of the primary mixture.

Herein is disclosed a method of printing comprising the steps of: (a) applying an ink comprising a thermoplastic resin to a print substrate using an electrostatic printing process; and (b) applying an overcoat composition comprising a crosslinking agent to the ink on the print substrate, such that the thermoplastic resin of the ink is crosslinked. Print substrates and printing systems are also disclosed.

An image forming method includes: forming a toner image on a sheet by using a toner including a first binder resin; and applying, to the toner image, a fixing solution capable of softening the first binder resin so as to fix the toner image to the sheet. The first binder resin is a condensate of a first alcohol component and a first carboxylic acid component. The first alcohol component contains 1,4-butanediol, and the first carboxylic acid component contains polyvalent carboxylic acid. A molar ratio of the 1,4-butanediol in the first alcohol component is not less than 30 mol %.

There is provided a fixing solution capable of improving fixing property while suppressing odor. The fixing solution includes: an aliphatic dicarboxylic acid ester; a polyethylene glycol alkyl ether; and water. The water is dispersed in the aliphatic dicarboxylic acid ester. The polyethylene glycol alkyl ether has not less than 4 pieces and not more than 12 pieces of an oxyethylene unit.

A fuser fluid composition is disclosed, including a non-fluorinated functional silicone fluid, and a non-fluorinated non-functional silicone fluid, where the non-fluorinated functional silicone fluid is present in the fuser fluid composition in an amount of from about 1 wt % to about 30 wt % based on a total weight of the fuser fluid composition, and the non-fluorinated non-functional silicone fluid is present in the fuser fluid composition in an amount of from about 50 wt % to about 99 wt % based on a total weight of the fuser fluid composition. The non-fluorinated functional silicone fluid may include an amine-functional group. A cleaning web and a fusing subsystem for a printing system may include a material impregnated with the fuser fluid composition.

The present invention is to provide a toner which has an excellent balance between heat-resistant storage stability and low-temperature fixability and which is excellent in printing durability even under a wide range of temperature and humidity environments from a low temperature and low humidity environment to a high temperature and high humidity environment. Disclosed is a toner for developing electrostatic images, containing colored resin particles containing a binder resin, a colorant, a softening agent and a retention aid, and an external additive, wherein the retention aid is a copolymer of at least one of acrylic acid ester and methacrylic acid ester and at least one of acrylic acid and methacrylic acid, and wherein the copolymer has an acid value of 0.5 to 7 mgKOH/g, a weight average molecular weight Mw of 6,000 to 50,000, and a glass transition temperature of 60 to 85 C.
