RECORDING MATERIAL CONVEYING DEVICE AND IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To appropriately determine the state of a conveying device that conveys a recording material.SOLUTION: A recording material conveying device 200 comprises: registration rollers 10 that convey a recording material P; a conveyance speed detection part 40 that detects the conveyance speed of the recording material P conveyed by the registration rollers 10; and a CPU 30 that determines a state where an attachment is attached to the registration rollers 10 or the state of wear of the registration rollers 10 on the basis of the distribution of changes in conveyance speed detected by the conveyance speed detection part 40.SELECTED DRAWING: Figure 2 【課題】記録材を搬送する搬送装置の状態を適切に判断すること。【解決手段】記録材搬送装置２００は、記録材Ｐを搬送するレジローラ１０と、レジローラ１０により搬送する記録材Ｐの搬送速度を検出する搬送速度検出部４０と、搬送速度検出部４０により検出した搬送速度の変化の分布に基づいて、レジローラ１０に付着物が付着した状態又はレジローラ１０の磨耗の状態を判定するＣＰＵ３０と、を有する。【選択図】図２
