<P>PROBLEM TO BE SOLVED: To solve the problem in which: it is difficult to accurately control conveyance speed of a recording material in an image forming apparatus if controlling a driving source requiring a feedback control such as a DC motor by a control system using a fixed control constant in all sections since optimum control systems for controlling the conveyance speed of the recording material are different according to the sections with the recording material conveyed therein. <P>SOLUTION: A control section suitable for each section is selected according to the section in which the recording material P is conveyed and the control constant capable of performing follow-up control suitable for each section is set. Accordingly, a control with excellent control performance can be performed as compared with a case where the conveyance motor is controlled by the consistently even control section and control constant. Even when a motor requiring the feedback control such as the DC motor is used as the driving source, lowering of followability can be suppressed when acceleration/deceleration controlling the conveyance speed of the recording material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
