Title: Toner-guiding sheet, cleaning apparatus, process cartridge, and image forming apparatus

Abstract: A toner-guiding sheet for guiding toner removed from an image carrying member. The sheet includes a free end portion for contacting a surface of the image carrying member, and a fixed portion, fixable on a fixing member, for fixing the toner-guiding sheet in a state in which the free end portion contacts the surface of the image carrying member. The toner-guiding sheet includes a film having a creep-deformation resisting property such that, when the film, fixed on the fixing member so that a distance .beta. from a central portion in a longitudinal direction of the fixed portion of the sheet to a central portion in a longitudinal direction of the free end portion of the sheet is substantially 3.86 mm, is brought in contact with a surface of a contact member under conditions such that a distance .alpha. from the central portion in the longitudinal direction of the fixed portion of the sheet to a central portion in the longitudinal direction of a contact portion of the free end portion on the surface of the contact member is substantially 1.86 mm, an amount of penetration .delta. of the central portion in the longitudinal direction of the contact portion of the sheet with respect to the contact member is substantially 2.0 mm, and an amount of charge .xi. of the central portion in the longitudinal direction of the contact portion of the sheet with respect to the contact member is substantially 0.74 mm, a change in the amount of penetration .delta. when leaving the toner-guiding sheet in an environment of a temperature of substantially 45.degree. C./a humidity of substantially 60% RH for substantially 30 days is equal to or less than substantially 0.43 mm.
