<p>PROBLEM TO BE SOLVED: To provide a yellow developer having excellent light-transmitting property and color reproducibility for an OHP and having excellent transfer property. SOLUTION: This developer is used for a full-color image forming method to reproduce a multicolored image. The developer contains negative charge nonmagnetic toner particles containing a binder resin having 1 to 30 KOHmg/g acid value, a compd. classified as a pigment yellow 180, and a compd. expressed by formula. In the formula, R1 , R2 are independently hydrogen atoms, 1 to 5C alkyl groups or -(CH2 )XCOOR5 groups (R5 is a hydrogen atom or lower alkyl group and X is an integer 1 to 3), R3 , R4 are hydrogen atoms, halogen atoms, or 1 to 12 C alkyl groups or aryl groups which may have branches, (l) is an integer 4 to 8, (m) is an integer 0 to 4, and (l+m) are 4 to 8.</p> |
