Air cushioning material

Provided is an image forming device in which a wrapped body that is a paper bundle wrapped in wrapping paper is set into a paper housing, the wrapping paper is subsequently removed and the paper bundle is exposed, and paper is conveyed by one sheet in image forming, the image forming device including: a reader that reads an image on the wrapping paper; and a hardware processor that: compares the image on the wrapping paper, the image being read by the reader, and an image on each of various kinds of wrapping paper, the image being stored in a storage; reads, from the storage, paper setting associated to wrapping paper corresponding to the image on the wrapping paper, the image being read by the reader; and sets a conveyance condition and a process condition based on the paper setting.

Image forming device and image forming system

Provided are an accommodating device that performs appropriate processing in order to discard an empty paper pack remaining in the accommodating device and an image forming apparatus including the accommodating device. The accommodating device includes an accommodating unit, a processing unit, and a discarding unit. The accommodating unit accommodates a paper pack including a bundle of stacked sheets of printer paper wrapped with wrapping paper in such a manner that the printer paper is freely taken out. The processing unit flatly crushes and conveys an empty paper pack from which all of the sheets of the printer paper have been taken out and in which only the wrapping paper has remained. The discarding unit stores a flatly crashed empty paper pack conveyed from the processing unit in order to discard them.

Accommodating device and image forming apparatus

A developing device having: a developing sleeve in which a magnetic member is inserted, transporting two-component developer to a developing area facing an image carrier; and a restriction member for restricting the amount of developer to be no greater than 250 g/m. The average of absolute values of magnetic flux density within a restriction area falls within a range of 40 mT to 70 mT under a condition that no developer exists within the restriction area. The restriction area extends along the outer circumferential surface between a closest point on the outer circumferential surface, which is closest to the restriction member, and a point 2 mm upstream from the closest point in a rotational direction of the developing sleeve, and has a height that is half a minimum distance between the closest point and the restriction member.

Developing device and image forming apparatus

A developing device having: a guide member creating a guide channel for guiding the developer being fed thereto while being supported on the developer support; and a regulating member regulating the amount of the developer that has passed through the guide channel, the guide member further creates a reflux channel in a gap from an inner surface of the housing, the reflux channel is connected to the guide channel via a communication channel such that the developer regulated by the regulating member returns toward an upstream end of the guide member, the upstream end of the guide member is disposed in a position opposed to the position where the magnetic flux density of the catch pole peaks, and the magnet assembly further includes a feeding pole that is disposed downstream of the catch pole and upstream of the developing pole, so as to be opposed to the guide channel.

Developing device and image forming apparatus including same

A development device having: a main unit having formed therein a first space and a second space extending in a first direction perpendicular to a vertical direction, a first communicating portion and a second communicating portion that allow the first space and the second space to communicate with each other at both ends in the first direction; a first stirring member that extends in the first direction within the first space; a second stirring member that is positioned within the first space between the first stirring member and the second space and extends in the first direction; a conveyance member that extends in the first direction within the second space; and a developer support member that extends in the first direction within the second space.

Development device
