摘要： An image forming apparatus includes a latent image bearer; a developing device containing two-component developer and including a developer bearer, a development voltage source, and a toner concentration detector; a toner supply device to supply toner to the developing device; a transfer device; and a controller to keep a toner concentration in the developer in the developing device at a target toner concentration during image formation. The controller executes forced toner consumption in which the developing device supplies the toner to the latent image bearer the toner at a predetermined forced toner consumption timing, while inhibiting the toner supply device from supplying toner. When the toner concentration falls to a prescribed toner density lower than the target toner concentration, the controller completes the forced toner consumption and executes a post-consumption toner supply operation.

摘要翻译： 图像形成装置包括潜像载体; 包含双组分显影剂并包括显影剂承载体的显影装置，显影电压源和调色剂浓度检测器; 调色剂供应装置，用于向显影装置供应调色剂; 转移装置; 以及控制器，用于在图像形成期间将显影装置中的显影剂中的调色剂浓度保持在目标调色剂浓度。 控制器执行强制调色剂消耗，其中在抑制调色剂供应装置供应调色剂的同时，显影装置以预定的强制调色剂消耗时间将调色剂供给到潜像承载调色剂。 当调色剂浓度降低到低于目标调色剂浓度的规定调色剂浓度时，控制器完成强制调色剂消耗并执行消耗后调色剂供应操作。
