Zusammenfassung: | To provide a developer supply device that can efficiently supply liquid developer from a supply roller that rotates carrying the liquid developer to a developing roller.SOLUTION: A supply roller 51 to rotate carries liquid developer, a guide plate 52 removes liquid developer on the supply roller 51, and liquid developer is supplied to a developing roller 17. The supply roller 51 and the developing roller 17 are not in contact with and spaced apart from each other. The guide blade 52 is provided so as to be laid between the supply roller 51 and the developing roller 17 spaced apart from each other to guide the liquid developer from the supply roller 51 to the developing roller 17. That is, the liquid developer carried by the supply roller 51 is not separated and supplied to the developing roller 17, but the liquid developer removed by the guide blade 52 is supplied to the development roller 17. The supply of the liquid developer by the guide blade 52 can supply the liquid developer more efficiently than the liquid developer supplied by separation.SELECTED DRAWING: Figure 2
【課題】液体現像剤を担持して回転する供給ローラから現像ローラに対し液体現像剤を効率的に供給可能な現像剤供給装置の提供。【解決手段】回転する供給ローラ51に液体現像剤を担持させ、案内ブレード52によって供給ローラ51上の液体現像剤を掻き取らせて、現像ローラ17に液体現像剤を供給する。供給ローラ51と現像ローラ17とは非接触に離間配置され、案内ブレード52は離間されている供給ローラ51と現像ローラ17との間を架け渡すように設けられて、供給ローラ51から現像ローラ17へ液体現像剤を案内する。即ち、供給ローラ51に担持された液体現像剤がなきわかれて現像ローラ17に供給されるわけでなく、案内ブレード52によって掻き取られた液体現像剤が現像ローラ17に供給される。この案内ブレード52による液体現像剤の供給は、なきわかれによる液体現像剤の供給に比較して、より効率的に液体現像剤を供給できる。【選択図】図2 |
