An image forming apparatus in which the consumption article can be attached to and detached from a main body has a controller, which reads first new/old information that is stored in a repetitively rewritable area of a memory provided on the consumption article and represents whether or not the consumption article is unused after manufacturing or after recycling and second new/old information that is stored in a once rewritable area of the memory and represents the number of times of recycling of the consumption article and controls the operation of the image forming apparatus on the basis of the first new/old information and the second new/old information.
摘要:
An image forming apparatus, in which a consumption article can be attached to and detached from a main body, has a device that makes an access to a memory provided on the consumption article, a device that determines whether or not an access failure has occurred during the access to the memory, and a device that switches over between warning levels according to the address of the memory where the access failure has occurred or an attribute concerning write and read where the access failure has occurred.
摘要:
An image forming system having an image forming apparatus and a post-processing apparatus having a sorting function, a stapling function, etc. The post-processing apparatus is movable between a first position to receive long papers and a second position to receive non-long papers. When the post-processing apparatus is set in the second position, a paper inlet port of the post-processing apparatus faces a paper ejection port of the image forming apparatus.

摘要:
Image forming apparatus is equipped with a memory for storing additional images and an area discriminating unit for discriminating areas included in document images. The area discriminating unit discriminates text areas included in a document image based on the cyclicity of the density distribution of the document image. An additional image stored in the memory is synthesized into a discriminated text area. On the other hand, no additional image is synthesized into graphic areas and photograph areas. Images obtained as a result of the syntheses of document images and additional images are printed out on paper.

A copying machine with a charging device that can substantially improve the advertisement effect in case of printing by adding an additional image to a document image. This copying machine, when the set registered number is plural, changes the kind of advertisement images to be printed every time a document is exchanged. It also changes the kind of advertisement images depending on whether or not a copying mode is a color copy. In particular, if it is the color copy, the above-mentioned changeover is done in accordance with a function mode and/or a document mode, which are detail modes of the color copy. This copying machine also displays a plurality of printable selection candidates from a plurality of advertisement images stored in advance and makes a user on his/her own select an advertisement image to be printed. In this case, a selection condition of the advertisement image by the user (kind or order of the selection candidates to be displayed, or number of selectable advertisement images, for example) is changed in accordance with an environment when the user copies the document (copying mode, current time, or installation location, for example).
摘要:
An image forming apparatus, such as an electrophotographic copier, forms a test image on a photosensitive member, under constant image forming conditions, and the amount of toner adhering to the photosensitive member is detected. The detected amount of toner is converted into a developer toner concentration, based on a conversion standard. The toner concentration is used to control the operation of a toner replenishment device. The conversion standard is periodically corrected by forming a test image using a developer having a known toner concentration, detecting the amount of adhered toner, comparing the detected result to a standard value, and selecting one conversion standard table from among a number of different conversion tables.
摘要:
The image forming apparatus is provided with a detecting means for detecting transfer efficiency when transferring a toner image from a photosensitive member to a transfer sheet, and a developing efficiency changing means for changing developing efficiency based on the transfer efficiency detected by the detecting means, and corrects the toner consumption predicted by the predicting means based on the transfer efficiency as detected by the detecting means, so as to determine the amount of toner to be replenished. When the developing efficiency is changed based on the transfer efficiency, toner consumption also changes, and does not match the predicted toner consumption. According to the present invention, toner concentration in a developer can be even more accurately controlled by correcting the predicted toner consumption by the change in transfer efficiency. Detection of transfer efficiency is achieved by a method of indirectly detecting humidity in the apparatus, or a method of measuring the amount of toner transferred to a transfer member.
摘要:
A polyamide resin composition is provided which contains an anti-aging agent together with a deterioration inhibitor, such as a metal compound or a silica-based inorganic compound, for preventing deterioration caused by, for example, an acid component or a halogen component contained in a refrigerant or an oil, and which satisfactorily produces an anti-aging effect expected by adding the anti-aging agent. For producing a polyamide resin composition containing an (a) polyamide resin, a (b) polyolefin-based elastomer, at least one (c) deterioration inhibitor selected from the group consisting of hydroxides, oxides and basic salts of divalent or trivalent metals, and silica-based inorganic compounds, and a (d) anti-aging agent, a mixture prepared by mixing and kneading the (c) deterioration inhibitor and (b) polyolefin-based elastomer and a mixture prepared by mixing and kneading the (a) polyamide resin and the (d) anti-aging agent are mixed and kneaded.
