| 发明名称 | Image forming apparatus with control section to control contact pressure between heating member and pressure member and control method thereof | ||
| 摘要 | An image forming apparatus is provided that includes: a heating member that heats a recording sheet; a pressure member that presses the recording sheet between the heating member and the pressure member; an adjustment mechanism that causes the heating member and the pressure member to contact or to separate; and a control section that, at a time of a warm-up operation or an idling operation, based on a predetermined condition, controls the adjustment mechanism so as to cause the heating member and the pressure member to contact at a contact pressure that is lower than a contact pressure between the heating member and the pressure member at a time of image formation or is approximately identical to the contact pressure at a time of image formation. | ||

| 主权项 | 1. An image forming apparatus, comprising: a heating member that heats a recording sheet; a pressure member that presses the recording sheet between the heating member and the pressure member; an adjustment mechanism that causes the heating member and the pressure member to contact or separate; and a control section that, at a time of a warm-up operation or an idling operation, if an elapsed time after power-off of the image forming apparatus is greater than or equal to a predetermined time, controls the adjustment mechanism so as to cause the heating member and the pressure member to contact at a contact pressure that is lower than a contact pressure between the heating member and the pressure member at a time of image formation or is approximately identical to the contact pressure at a time of image formation, while if the elapsed time is less than the predetermined time, the control section controls the adjustment mechanism so as to cause the heating member and the pressure member to contact at a contact pressure that is lower than a contact pressure between the heating member and the pressure member at a time of image formation. | ||
