    • In a laser beam printer, an elastic conductive member is disposed between a rotating axis of a transfer roller and a land portion of a power supply circuit board and the transfer roller is electrically connected to the power supply circuit board through the elastic conductive member. A front end portion of the elastic conductive member is pressed onto the land portion by its elastic force to come into contact with a solder pad formed on the surface of the land portion for electrical connection. A resist film is partially formed on the surface of the land portion and the solder pad is formed on the region on the land portion that is not covered with the resist film. Thus, a large contact area between the front end portion of the elastic conductive member and the solder pad is ensured so as to address a high voltage applied to the transfer roller. As a result, the transfer roller, etc. can be electrically connected to the power supply circuit board with certainty without increasing the number of components.
    • 在激光束打印机中,弹性导电构件设置在转印辊的旋转轴线和电源电路板的接地部之间,并且转印辊通过弹性导电构件电连接到电源电路板。 弹性导电部件的前端部通过其弹性力被压接到台肩部上,以与形成在焊盘部分的表面上的焊接焊盘接触以进行电连接。 在焊盘部分的表面上部分地形成抗蚀剂膜,并且在没有被抗蚀剂膜覆盖的焊盘部分上的区域上形成焊盘。 因此,确保弹性导电构件的前端部与焊盘之间的大的接触面积,以解决施加到转印辊的高电压。 结果,转印辊等可以确实地电连接到电源电路板,而不增加部件的数量。
