FIELD: printing industry.
SUBSTANCE: group of inventions contains a toner, a developer and an image forming apparatus. Wherein toner contains pigment, polyester resin A, insoluble in tetrahydrofurane (THF), and polyester resin B, soluble in tetrahydrofurane (THF), where the toner satisfies (1)-(3): (1) polyester resin (A) includes one or more aliphatic diols, including from 3 to 10 carbon atoms, as a component of polyester resin (A), (2) polyester resin (B) includes at least alkylen glycol in quantities of 40 mol.% or more as a component of polyester resin (B), and (3) toner glass transition temperature (Tg1st) in the first heating when measuring toner by differential scanning calorimetry (DSC) ranges from 20°C to 50°C.
EFFECT: provision of toner with excellent potential for low-temperature record, resistant to hot offset, thermal stability during storage and stability resistance to moisture and thermal stability at storage, and glossiness of image.
