Summary:PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that reduces the generation of fine colored lines when applied to an image forming apparatus of a system that applies only a DC voltage to a charging member in contact with the electrophotographic photoreceptor to charge the electrophotographic photoreceptor.SOLUTION: An electrophotographic photoreceptor comprises a conductive substrate, and a photosensitive layer provided on the conductive substrate. Supposing that the time from when application of a rectangular voltage to the electrophotographic photoreceptor is started until when a current value reaches the maximum value is T, and the time from when the application of the rectangular voltage is started until when the current value reaches the maximum value and then drops to one-fifth of the maximum value is T, Tis 3.2 times Tor more and 11.0 times Tor less.SELECTED DRAWING: None 【課題】電子写真感光体に接触する帯電部材に直流電圧のみを印加して電子写真感光体を帯電する方式の画像形成装置に適用した場合における微小色線の発生を抑制する電子写真感光体を提供する。【解決手段】導電性基体と、導電性基体上に設けられた感光層と、を有し、電子写真感光体に対する矩形電圧の印加を開始してから電流値が最大値に達するまでの時間をＴ１、矩形電圧の印加を開始してから電流値が最大値を経て最大値の５分の１の値に下がるまでの時間をＴ２としたとき、Ｔ２はＴ１の３．２倍以上１１．０倍以下である電子写真感光体。【選択図】なし
