摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus which is made compact and free from poor image quality.
SOLUTION: The electrical resistance of an ion conductive transfer roll 28 tends to lower with a temperature rise, then, regarding the image forming apparatus including a fixing unit 34 provided near an exit and a conveying belt system having the layout traveling upward in nearly a vertical direction, the transfer roll 28 positioned on the upper side (on the downstream side) is more affected by fixation heat, and the temperature of the transfer roll 28 positioned on the upper side becomes higher due to the fixation heat, and then, the electrical resistance becomes lower. If the transfer electrical field is made higher from the upstream to the downstream in order to solve the situation, the excessive transfer electrical field is formed on the transfer roll 28 positioned on the downstream side, then, the image quality becomes poor as a result. In order to avoid such the failure, an apply voltage is made lower from the upstream to the downstream as it comes closer to the fixing unit 34, so as to prevent the excessive transfer electrical field on the downstream side.

摘要翻译：要解决的问题：提供一种成形紧凑且图像质量差的图像形成装置。解决方案：离子导电转印辊28的电阻随着温度升高而趋于下降，然后，关于包括设置在出口附近的固定单元34的图像形成装置和具有向上行进的布局的输送带系统几乎垂直方向，位于上侧（下游侧）的转印辊28受定影热影响较大，位于上侧的转印辊28的温度由于定影热而变高，然后，电阻变低。为了解决这种情况，如果从上游到下游的转移电场较高，则在位于下游侧的转印辊28上形成过剩的转印电场，结果，图像质量变差。为了避免这样的故障，当接近固定单元34时，从上游到下游施加施加电压，以防止下游侧的过度转印电场。版权所有（C）2008，JPO＆INPIT

SOLUTION: In order to arrange an image forming section 14 in a main body 16, a space, in which the image forming section 14 can be arranged, is required between a mounting surface 30 and a mounting surface 72 of the main body section 14. For the above purpose, a hand insertion tray 32 is arranged on top of the main body section 16 and an ejection tray 44 is arranged on the mounting surface 72 side of the main body section 16 to provide a gap H
1 between the hand insertion tray 32 and an ejection tray 44. Thus, even though a hand insertion tray 32 is provided on top of the main body section 16, visibility of a recorded sheet, that is ejected onto the ejection tray 44, is secured by the gap H
1 and the height of an image forming device 86 is suppressed by securing the visibility of a recording sheet using the size of the main body section 16.
