An image forming apparatus including a unit including image carriers for carrying electrostatic latent images, respectively, and developing devices for developing the electrostatic latent images with toners, respectively, and integrated with the image carriers, and toner feeding devices for feeding the toners to the developing devices, respectively, and provided separately from the unit, wherein the toner feeding devices and developing devices are detachably engaged with each other.

Image forming apparatus

An input device of a multimedia board inputs lecturer-written information that a lecturer writes on a display page. An information processor sends the lecturer-written information input by the input device to a plurality of information terminals. A reader/writer of each of the plurality of information terminals reads out textbook information from a recording medium recording the textbook information representing contents of a textbook. A display device displays the read textbook information and the lecturer-written information supplied from the information processor, which are superimposed one on top of the other. The reader/writer records the textbook information and lecturer-written information, which are displayed by the display device, as a single file on the recording medium.

System for facilitating teaching and learning

The present invention is an enzyme-decomposable polymer compound having recyclable decomposition products. The polymeric compound is a glycopolymer of a saccharide having only glucopyranose rings and a second component. In addition, the glycopolymer may contain molecular chains having at least one type of repeating unit, which chains are crosslinked by a saccharide having only glucopyranose rings.

Polymeric compound comprising glycopolymer and a method for decomposing the same

An image forming apparatus including a plurality of imaging units each for forming an image on a recording medium, an image carrier provided in each of the plurality of imaging unit, a development unit for visualizing an electrostatic latent image on the image carrier by toner in each of the plurality of imaging units, and a supporting device configured to integrate at least two imaging units of the plurality of imaging units into a unit, wherein the supporting device has a plurality of pressing members configured to press upper portions of the at least two imaging units, respectively, and a plurality of supporting members configured to support lower portions of the at least two imagining units, respectively.

Image forming apparatus having a supporting device for supporting imaging units

A recycling system has a recycle information memory database for storing as recycle information, the information on all reutilizable products such as products produced or used under the management of the system, products treated as wastes, and products currently being used in the market. A virtual recycle product designing section is provided for estimating times when the reutilizable products are recovered as products usable for recycling as well as their volumes, based on the recycle information stored in the recycle information memory database. A production scheduling section is provided for setting a production schedule of a recycle product using the reutilizable products based on the estimated times and volumes.

Recycling system and recycling method

An image forming apparatus has an electrophotographic photosensitive member with a support, a photosensitive layer with a thickness (T), a charging subunit, an exposure subunit, a developing subunit, and a transfer subunit. The exposure subunit illuminates the charged photosensitive member with a light beam having a spot area (S), such that the product S.times.T is 5,000-12,000 .mu.m.sup.3.

This invention provides a transparent thermal recording medium, in which the transparent thermal recording medium comprises: a thermal recording layer, which is provided on a transparent layer, consisting essentially of an electron-donating chromophoric compound, an electron-accepting compound and binder resin; and a further-provided protective layer having an approximately equal refractive index to the refractive index of the thermal recording layer, wherein the binder resin is a compound having a group selected from a hydroxyl group and a carboxyl group. The transparent thermal recording medium can be effectively used for a block copy film, on which an image is formed, for plate-making, particularly, in photogravure, offset printing and screen process printing, because the transparent thermal recording medium has a contrast of light transmission factors between a color-imaging portion and a non-imaging portion, in which the contrast is not less than 50% at a wavelength ranging from 370 nm to 450 nm.

Transparent thermal recording medium

An electrophotographic photosensitive member, has an electroconductive support, an interlayer, and a photosensitive layer provided in the order named. The interlayer contains a polyamide having a structural unit represented by the formula (I) below: ##STR1## wherein R.sub.1 is a substituted or unsubstituted alkyl group, R.sub.2 is a substituted or unsubstituted alkylene group, and n is an integer of one or more.

There is provided a transfer material carrying member and an image forming apparatus using it. The transfer material carrying member comprises a metal oxide and a polycarbonate resin having a repeating unit represented by the following formula: ##STR1## The transfer medium carrying member of the present invention has superior surface electrical characteristics, mechanical strength and transparency. The image forming apparatus making use of the transfer medium carrying member enables consistently good transfer even when copies are repeatedly taken and makes it possible to obtain consistently stable, good images.

Transfer material carrying member and image forming apparatus

A transfer material carrying member has a copolymer and conductive particles; the copolymer has a component unit represented by the Formula (I) and a component unit represented by the Formula (II), and the component unit represented by Formula (II) is in an amount of from 0.1% by weight to 50% by weight based on the total weight of the copolymer.

Transfer material carrying member and image forming apparatus making use

An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on an electroconductive support. The photosensitive layer is characterized by containing a specific polycarbonate having a side chain comprising a charge-transporting group formed by nitrogen atom and benzene ring. The charge-transporting group may preferably has a specific triphenylamine structure, hydrazone structure or biphenyldiamine structure.
