Abstract:
A toner-guiding sheet for guiding toner removed from an image carrying member, comprising: a free end portion for contacting a surface of the image carrying member; and a fixed portion, fixable on a fixing member, for fixing said toner-guiding sheet in a state in which said free end portion contacts the surface of the image carrying member, wherein said toner-guiding sheet comprises 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 said fixed portion of said sheet to a central portion in a longitudinal direction of said free end portion of said 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 said fixed portion of said sheet to a central portion in the longitudinal direction of a contact portion of said 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 said contact portion of said 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 said contact portion of said sheet with respect to the contact member is substantially 0.74 mm, a change in the amount of penetration .delta. when leaving said 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 0.43 mm.
