ABSTRACT:
When a status transition occurs, case data are collected and a new control rule is generated based on those case data. A control rule memory can store a plurality of control rules. A plurality of control rules are selectively read out from the control rule memory, and combined in accordance with their adaptabilities into an application control rule. An error between a target value and a measured control quantity is applied to the application control rule, to thereby calculate a correction value of an operation quantity. An operation part of an image forming apparatus main body is controlled based on the correction value so that the control quantity becomes the target value.
