摘要： A switching transistor has a source connected to the ground and a drain connected to the first terminal. The other end of an inductor whose one end is to be connected to the first terminal is connected to the second terminal. An input voltage is applied to the third terminal. An auxiliary transistor is disposed between the second terminal and the third terminal. A first soft start circuit generates a first soft start voltage that increases with lapse of time, and a second soft start circuit generates a second soft start voltage that increases with a delay to the first soft start voltage. An error amplifier controls the gate voltage of the auxiliary transistor on the basis of the error voltage between the output voltage and the first soft start voltage.

摘要： A lubricant application device including a solid lubricant, a brush, and a first lubricant scattering prevention member. The solid lubricant is in a non-contact state with a rotating member and provided below a horizontal line of an axis of the rotating member. The brush rotates and contacts both the solid lubricant and the rotating member. The first lubricant scattering prevention member is provided downstream from a first contact position at which the brush contacts the solid lubricant and upstream from a second contact position at which the brush contacts the rotating member in a direction of rotation of the brush.

摘要： A charging device includes a charging roller, a drive transmission device, and a charging roller cleaner. The charging roller opposes an image carrier driven to rotate and rotates to charge the image carrier. The charging roller cleaner contacts the charging roller to clean the charging roller. The drive transmission device transmits torque from the image carrier to the charging roller, and includes an image carrier gear and a driven gear. The image carrier gear and the driven gear form a gear train to drive the charging roller in response to rotation of the image carrier. The charging roller cleaner is disposed facing a rear surface of the charging roller to prevent displacement of the charging roller due to a force generated by a pressure angle formed between the image carrier gear and the driven gear when the charging roller rotates in response to rotation of the image carrier.
摘要翻译：充电装置包括充电辊，驱动传动装置和充电辊清洁器。充电辊与被驱动旋转并转动以对图像载体充电的图像载体相对。充电辊清洁器与充电辊接触以清洁充电辊。驱动传动装置将图像载体的扭矩传递到充电辊，并且包括图像载体齿轮和从动齿轮。图像承载齿轮和从动齿轮形成齿轮系，以响应于图像载体的旋转来驱动充电辊。充电辊清洁器设置成面对充电辊的后表面，以防止当充电辊响应于图像载体齿轮和从动齿轮之间形成的压力角产生的力而响应于旋转时的充电辊的位移图像载体。
