    • The present invention provides an electric power steering apparatus, in which reduction and thickness thereof can be achieved, radiation performance thereof can concurrently be ensured, and manufacturing and running costs thereof can also be reduced, even when the apparatus includes a structure having a motor and a motor control device integrated therewith. The apparatus includes a motor which assists in steering operations, a motor control device which controls the motor, and a housing which accommodates the motor and the motor control device. The housing includes a motor accommodation portion which accommodates the motor, and a control device accommodation portion which accommodates the motor control device. The motor control device includes a drive unit which drives the motor, and a control unit which controls the motor. The drive unit is disposed in a position in the control device accommodation portion, the position being in proximity to the motor accommodation portion.

    • A developing device for an image forming apparatus of the present invention includes an image carrier performing endless movement while carrying a developer in the form of a layer thereon, and a regulating member for regulating the thickness of the layer Toner stored in the developing device is covered with an additive whose particle size is less than 2 &mgr;m. The regulating member is implemented as a doctor roller having a surface roughness Rz equal to or greater than the above particle size, but smaller than 2 &mgr;m. The doctor roller is pressed against a developing roller or developer carrier by a preselected pressure, forming a nip for development The developing device reduces irregular development ascribable to impurities caught at a regulating position assigned to the doctor roller more than a conventional developing device using a doctor blade as a regulating member. In addition, the developing device obviates irregular development in the form of fine stripes ascribable to stripe-like irregularities formed in the developer layer existing on the developing roller.
    • 本发明的图像形成装置的显影装置包括:图像载体,其在其上承载显影剂形式的显影剂的同时执行无限次移动,并且覆盖用于调节所述层的厚度的调节部件覆盖存储在显影装置中的调色剂被覆盖 具有粒径小于2μm的添加剂。 调节构件被实施为具有等于或大于上述粒径但小于2μm的表面粗糙度Rz的刮刀辊。 刮刀辊被预选的压力压在显影辊或显影剂载体上,形成用于显影的辊隙显影装置比使用医生的常规显影装置减少归因于分配给刮墨辊的调节位置上的杂质的不规则显影 叶片作为调节构件。 此外,显影装置避免了由于存在于显影辊上的显影剂层中形成的条状凹凸形状的细条状的不规则显影。
