A paper transfer apparatus is provided to separate connection shafts from rotation shafts to which transfer rollers are joined, thereby enabling a worker or a user to replace the transfer rollers easily without a use of a separate tool and disassembling an assembly and surrounding parts. A first connection shaft(18) and a second connection shaft(20) are penetrated into a second fixing bracket(14) in a state when parts of the first connection shaft and the second connection shaft are pulled out between a first fixing bracket(12) and the second fixing bracket fixed to both sides of a connection member(16). The first connection shaft and the second connection shaft are joined to a first transfer roller and a second transfer roller respectively. In the outside of the second fixing bracket, a first housing(26) and a second housing(28) are joined to the first and second connection shafts in a penetration type. A cut portion(30) is formed as much as a predetermined range along the circumference of the first housings. A first clip(32) is joined to the cut portion so that the first clip can be held on a holding groove(36) formed in the outside of the first connection shaft when the first connection shaft and the first rotation shaft(52) are joined to each other. The guide portion(40) of a support bracket(38) spaced from the outside of the second fixing bracket is disposed to surround a part of the second connection shaft and have a gap(44) with the second housing. A second clip(46) is joined to the gap so that the second clip can be held on a holding groove(50) formed in the outside of the second connection shaft when the second connection shaft and a second rotation shaft(54) are joined to each other. The joining portion(64) of the first rotation shaft and the joining portion(66) of the second rotation shaft are respectively penetrated into the first fixing bracket to be joined to sides corresponding to the first connection shaft and the second connection shaft in an insertion type.
