ABSTRACT:
A wiper, a cleaning device, and an inkjet image forming device including the wiper and the cleaning device. The cleaning device includes a carrier moving in a lengthwise direction of a nozzle unit, the length of the nozzle unit corresponding to a width of a printing medium, a driving element moving the carrier forwards and backwards, and a wiper mounted on the carrier and removing ink adhered to the nozzle unit, wherein the wiper includes a belt member which is supported by a plurality of pulleys and circularly moves along a predetermined path and a cleaning member which is attached to an outer circumference of the belt member and removes the ink adhered to the nozzle unit while rotating in contact with the nozzle unit. Accordingly, an absorption capacity of the wiper is increased using the belt type wiper. Furthermore, since the absorption capacity of the wiper is increased, a replacement cycle for replacing the wiper is extended, thereby increasing the life span of the wiper. The ink absorbed into the cleaning member is removed again using a second pressing unit or a cleaning roller, and hence the absorbency of the cleaning member can be maintained and the replacement cycle can be extended.
