Prediction Model of Development Characteristics and Toner Movements Based on Carrier Movements

Abstract

We developed a new prediction model which satisfy requirements of both calculation cost and accuracy. In two component development process, which is widely used for its suitability of high speed, high image quality, and colorization, huge number of carrier and toner particles that consist of developer are complexly moved while applied to several forces such as magnetic and electrostatic force. This leads to difficulty in high-precision and high-speed numerical simulation. We developed method to predict toner movements from carrier movements and toner properties by decomposing forces that is applied to toner based on intermediate characteristics between several development parameters and development characteristics. Important development characteristics such as developability, toner scattering, and bead-carry-out were simulated with high accuracy at low calculation cost.
