PROBLEM TO BE SOLVED: To prevent a user from being troubled by storing waste toner in a single waste toner hosing container altogether. SOLUTION: A branching carrying part 87 successively provided in a cleaning device 69 is arranged nearly perpendicularly to the device 69, and cleaning devices 71, 74 and 76 are arranged to be successively provided in a branching carrying part 88 through branching carrying parts 71a, 74a, and 76a. Two carrying parts 87 and 88 are focused to be one at the upper part of a focusing carrying part 95. Therefore, the waste toner carried from plural carrying parts 87, 71a, 74a, 76a and 88 is collected to one spot at the upper part of the carrying part 95. The waste toner carried from the carrying parts 87 and 88 by the carrying part 95 naturally drops, and by rotating a cylindrical member 96, the waste toner retaining in the middle of a screw blade is more surely carried in the waste toner housing container 85. A spiral groove is formed on the inner peripheral surface of the member 96. |
