摘要： There is provided an image forming device capable of preventing smudges on the background of an image due to excess toner replenishment caused by a failure in stirring developer and toner enough to charge the toner or scattering of replenished toner without being charged. A toner conveying member for conveying replenished toner from a toner replenishing portion through a toner replenishing port to a developer stirring and conveying member is constructed by a screw member unitarily formed with the developer stirring and conveying member. The screw member has a spiral conveying fin capable of conveying the replenished toner at relatively high speed. The replenished toner is delivered to a toner replenishing portion provided in the upstream of a developer receiving portion of the screw member.

摘要： A lubricant applying unit includes application mechanism that applies a lubricant from a solid lubricant on a surface of an image carrier that carries an image. The lubricant is a silicon-based-powder or a silicon-based-granule. Since the lubricant is less likely to adhere on a charging member that comes in contact with the image carrier, insufficient charge in the charging roller can be prevented, and a lifetime of the charging roller increases.
