PURPOSE:To shorten cleaning time and eliminate the unevenness of cleaning with simple construction, in an electrostatic printing device, by fixing a cleaning brush fitted with a paper cylinder to a brush fixing roller. CONSTITUTION:A brush fixing roller 16 is screwed to a drive shaft 12 directly coupled to an electric motor and rotates a cleaner brush 11 at 1,500rpm. The brush 11 is formed by a hollow cleaner brush paper cylinder 11' and a brush 11'', and is used by inserting the cylinder 11' onto the roller 16, and holding the opposite end with a guide cap 17. The roller 16 has a lock roller guide groove 13, in which the lock roller shaft 15 of a lock roller 14 moves. When the device rotates counterclockwise, the roller 14 presses and locks the cylinder 11' from the inner side while the shaft 15 is moving in the groove 13 in the circumferential direction of the roller 16, as the roller 16 rotates. In this locked state, the cleaning operation takes place. |
