The nonmagnetic monocomponent negatively chargeable color developer contains color toner particles that contain a chromatic color colorant, binder resin, and charge control agent, and an exterior additive added to the exterior of said toner particles. The binder resin is a linear polyester resin having a softening point of about 100.degree. to about 120.degree. C., the sum of the acid value and the hydroxyl value is about 20 to about 40 KOH mg/g, and the weight-average molecular weight/number-average molecular weight ratio is less than about 10. The charge controller is a boron compound having the general structural formula (A) below: ##STR1## wherein R.sub.1 and R.sub.8 is a substituted or nonsubstituted aryl groups; R.sub.2 and R.sub.4 is a member selected from the group consisting of hydrogen, alkyl group, substituted or nonsubstituted aryl group; X represents a cation, and n is an integer of either 1 or 2. The exterior additive is a hydrophobic silica and hydrophobic titanium dioxide in a hydrophobic silica. The hydrophobic titanium dioxide weight ratio is about 1:1 to about 1:3 by weight. The total specific surface area S of said exterior additive microparticles is about 100 to about 300 (m.sup.2 /g.multidot.wt %), and is determined by equation (1):S=(Ss.multidot.Vs)+(St.multidot.Vt) (1)wherein Ss is the specific surface area (m.sup.2 /g) of the hydrophobic silica; Vs is the additive amount (weight percent) of hydrophobic silica relative to the toner particle; St is the specific surface area (m.sup.2 /g) of the titanium dioxide; and Vt is the additive amount (weight percent) of titanium dioxide relative to the toner particle. The total amount of added exterior additive microparticles is about 0.8 to about 2.5 percent-by-weight relative to the toner particles.

    • An image data coding apparatus performs first and second coding processes. A controller outputs first and second control signals. An orthogonal transform circuit performs orthogonal transform on image data of one screen and generates an transformed output. A quantizing circuit quantizes the transformed output with a predetermined temporary first quantization width upon reception of the first control signal and generates a first quantized output, and quantizes the transformed output with an optimal second quantization width upon reception of the second control signal and generates a second quantized output. An entropy coding circuit codes the first quantized output and generates a first coded output, and codes the second quantized output and generates a second coded output. An amount-of-codes calculator calculates the amount of codes of the first coded output for each block and calculates the amount of codes of one screen based on the amount of codes for each block. An assigned-amount-of-codes determining circuit determines the amount of codes assigned to each block based on the amount of codes for each block and the amount of codes of the one screen, and the target amount of codes. A quantization width predicting circuit predicts the second quantization width based on the amount of codes of the one screen. A coding stop circuit supplies a coding stop signal to the entropy coding circuit when the amount of codes of the second coded output exceeds the assigned amount of codes.
