摘要： A lubricant application apparatus including a lubricant application member and an elastic member. The lubricant application member applies lubricant to a lubricant receiving member moving in a given surface movement direction. The elastic member contacts the lubricant receiving member in a counter direction with respect to the surface movement direction of the lubricant receiving member, and smoothes the lubricant applied on the lubricant receiving member. The elastic member is in contact with the lubricant receiving member at a contact area of the elastic member, in the counter direction. The elastic member is positioned in a downstream side of the surface movement direction of the lubricant receiving member with respect to the contact area of the elastic member. The elastic member is in contact with the lubricant receiving member at the contact area with a contact angle of 85 degrees or more.

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.
