A cleaning apparatus for a fixing device wherein a movable cleaning web is brought into contact with a member of the fixing device to thereby clean the fixing member. The amount or time of rotation of a take-up shaft for taking up the cleaning web is reduced stepwise depending on the number of sheets of recording paper having been subjected to image recording. The amount or time of rotation of the take-up shaft is effected by using the relationship between the increase in the diameter of the take-up roller and the number of copies made stored previously.

Cleaning apparatus for heat fixing device wherein the amount of cleaning

Disclosed is a recording sheet feeding apparatus for feeding recording sheets singly to a copying machine, comprising a sheet storage cassette for storing the recording sheets, a conveyance roller for conveying the recording sheets from the sheet storage cassette to a feeding roller, the feeding roller for feeding the recording sheets conveyed from the sheet storage cassette to the copying machine, a sheet separation roller, in contact with the feeding roller, for separating one of the recording sheets from other recording sheets so that the recording sheets are fed to the copying machine singly, and a rotation resister for resisting the rotation of the sheet separation roller by frictional resistance of a resistant member in which the sheet separation roller is further capable of rotating in an opposing direction to the feeding roller by the resiliency of a spring so that the other recording sheets separated by the sheet separation roller are fed back towards the sheet storage cassette.
