    摘要： A squeeze roller retraction assembly for use with electrophotographic copying machines of the type in which a photosensitive drum is removable from the machine, for inspection or other purposes, through an opening formed in a sidewall which opening is normally covered by a coverplate. A squeeze roller which normally engages with the peripheral drum surface has its engagement therewith automatically released once the coverplate has been dismounted from the sidewall, and also is returned to its operative position as the coverplate is remounted, to thereby prevent damage of the drum as well as a wrong usage of the machine which may be caused by forgetting to replace the squeeze roller to the operative position.

    摘要： A developer replenishing device for replenishing a developing device with a developer, and a developer container for use therewith. The developer container, or toner bottle, has a mouth portion at one end thereof which is smaller in diameter than a hollow cylindrical main body. At the end of the bottle provided with the mouth, a shoulder has the inner periphery thereof partly raised to the edge of the mouth portion to form a raised portion for scooping up a toner. In addition, a part of the inner periphery of the circumferential wall of the bottle which is contiguous with the raised portion is also raised toward the axis of the bottle about which the bottle is rotatable, thereby forming another raised portion. When the bottle is mounted to a bottle holder, which is included in the replenishing device, substantially horizontally with the mouth portion oriented sideways, the bottle is rotated to raise the toner from the bottom of the main body to the mouth portion. As a result, the toner is discharged to the outside via the mouth portion smoothly.
