After a brief introduction of Kondo Theory on the development by high resistance magnetic toners, some experimental results are given on the dependence of development characteristics (e. g., Q-V₀ and M-V₀ curves) upon the difference of development conditions, such as thickness of photoconductor (d), photoconductor to roller spacing (g_P), toner resistance (R_b), intensity of magnetic field (B), kind of latent images and the radius of toner particles (r).
From the analysis of these experimental data, it is proved that a sufficient agreement is obtained between the theoretical and experimental effects of the above development conditions on the numerical values of threshold voltage (V_k), the slopes of Q-V and M-V₀ curves (tan θ₁ and tan θ₂), the charge to mass ratio of toner particles (q/m), the equivalent thickness of toner brush (D_b) and so on.
