Abstract: A sheet feeding device includes: a sheet stacking unit that stacks a bundle of sheets; a pick-up roller that is enabled to move up and down and sends a sheet of the bundle of sheets toward downstream side in a carrying direction; a pair of rollers that is arranged at downstream side in the carrying direction, and when multiple sheets are sent out by the pick-up roller, that separates the first sheet from the second sheet or later; a separation member that is arranged between the pick-up roller and the pair of rollers and that is in contact with a leading end of the sheet and limits the number of the sheet carried to the pair of rollers; and a hardware processor that determines a height position of the pick-up roller corresponding to a type of the sheet and sets the pick-up roller to be at the determined height position.

Abstract: There is provided an image forming device having a guide member that guides a sheet having passed through a fixing device to a pair of sheet ejection rollers, wherein the pair of sheet ejection rollers has pairs of sub-rollers installed at a rotary shaft at predetermined intervals, and a nip is formed by a pair of sub-rollers facing each other, the pairs of sub-rollers includes a specific pair of sub-rollers that nips an end region in a width direction orthogonal to a sheet conveyance direction when a sheet of a prescribed size passes, and the guide member includes a pressing member that presses a curl caused at an end region in the width direction of the sheet on a more upstream side in the sheet conveyance direction than a position where a leading end of the sheet enters a nip between the specific pair of sub-rollers.

Abstract: A sheet is discharged from between a discharge roller and a feeding roller as pinched between the rotating discharge roller and feeding roller. In this arrangement, a guide is arranged from an upstream side to a downstream side in a sheet discharge direction. The guide is arranged to contact the discharge roller at a downstream position in the discharge direction from a position where the discharge roller contacts the feeding roller.

Abstract: A powder collecting device for conveying toner, a developer, waste toner and/or a waste developer in a conveyance pipe in one direction and for dropping it into a container through an opening made at an end of the conveyance pipe. The container is mountable in a body of an image forming apparatus such that the end of the conveyance pipe is inserted into the container, and is dismountable therefrom. An elastic sealing member, which has a larger area than a cross-sectional area of the end of the conveyance pipe, is attached to a portion of the container through which the end of the conveyance pipe is inserted into the container. A plurality of cuts are made in the sealing member such that the sealing member has at least an upper flap having a longer elastically deformable portion and a lower flap having a shorter elastically deformable portion.

Abstract: A storage unit stores first filter information specifying the formats of messages and second filter information specifying weights for words or phrases. A first search unit selects messages matching the formats specified by the first filter information from a plurality of messages as messages to be extracted. A second search unit calculates the importance level of each message unselected by the first search unit, based on the words or phrases included in the message and the second filter information, and selects messages to be extracted, according to the calculated importance levels from the messages unselected by the first search unit.
