Summary:PROBLEM TO BE SOLVED: To prevent dropping of residual toner from a leakage prevention sheet while suppressing costs.SOLUTION: A cleaning device comprises: the leakage prevention sheet contacting with an image carrier to prevent toner removed by a cleaning blade from leaking from a cleaning frame body; and an edge seal provided at an edge of the cleaning blade to prevent the toner from leaking to the outside of the cleaning frame body from the edge of the cleaning blade when the cleaning blade removes the toner. The edge seal comprises a first portion contacting with the image carrier and a second portion contacting with the leakage prevention sheet to press the leakage prevention sheet against the image carrier. A contact pressure per unit area of the second portion contacting with the leakage prevention sheet is smaller than the contact pressure per unit area of the first portion contacting with the image carrier. 【課題】コストを抑えつつ、漏洩防止シートからの残留トナーのボタ落ちを防止する。【解決手段】像担持体に接触し、クリーニングブレードによって除去されたトナーがクリーニング枠体から漏れることを防ぐ漏洩防止シートと、クリーニングブレードの端部に設けられ、クリーニングブレードがトナーを除去する際にトナーがクリーニングブレードの端部からクリーニング枠体の外部に漏れることを防ぐ端部シールとを具備し、端部シールは、像担持体に接触する第１の部分と、漏洩防止シートに接触して漏洩防止シートを像担持体に押し付ける第２の部分とを有し、第２の部分が漏洩防止シートに接触する単位面積当たりの接触圧は、第１の部分が像担持体に接触する単位面積当たりの接触圧よりも小さいことを特徴とするクリーニング装置。【選択図】 図５
