摘要:
An image output control apparatus is constructed by a converter for converting first information to second information, a controller for starting an output preparing operation before the conversion of the first information of one page to the second information, a memory for holding a control value determined during the output preparing operation, a unit for temporarily stopping the output preparing operation, and a unit for restarting the output preparing operation, wherein the output preparing operation to be restarted is executed on the basis of the control value held in the memory.
摘要:
An image forming apparatus including an image bearing member for bearing an image thereon, an intermediate transfer member having a base body and an elastic member provided outside the base body and onto which an image is transferrable from the image bearing member, and a second transfer member forming a nip portion between the second transfer member and the intermediate transfer member, for transferring an image from the intermediate transfer member to a transfer material in the nip portion. The hardness of the surface of the second transfer member is greater than the hardness of the surface of the intermediate transfer member.

A color image forming apparatus is provided with a number of image stations respectively corresponding to different color components and adapted to form images of respectively corresponding color components in succession and in superposed manner on a recording medium transported through the a number of image stations. The apparatus has memories for storing image data of respective color components to be supplied to the image stations, detectors for detecting aberration in registration of the images of respective color components formed by the image stations, and a controller for controlling the write-in positions of the image data of respective color components into the memories, based on the output of the detector.
摘要:
A developing apparatus includes an image bearing member for bearing an electrostatic image, a developer carrying member, opposed to the image bearing member to form a developing zone therebetween, for carrying a developer to the developing zone to develop an electrostatic latent image on the image bearing member, and oscillating bias means for applying an oscillating bias to the developer carrying member, wherein the oscillating bias includes a constant-current-controlled AC component and a constant-voltage-controlled DC component.
摘要:
An image forming apparatus includes an image bearing member; a device for forming a toner image on the image bearing member; an intermediate transfer member for receiving the toner image from the image bearing member; and wherein the intermediate transfer member has an average surface roughness which is smaller than one half a size of one pixel.

In a fixing device, a core material of a fixing rotating member has two largest-diameter portions respectively located between a central portion and each end portion of the fixing rotating member, within a region where a recording material of a largest size passes, and the diameter of each core material is gradually reduced from the largest-diameter portion toward the central portion and toward the nearest end portion. The outer shape of the fixing rotating member conforms to the shape of the core material. According to this configuration, it is possible to prevent corrugation and curl of the recording material, and to provide excellent mountability of the recording material.
摘要:
In a mobile radio communication system of a multi-layer cell structure for covering service areas in layers with cells of different sizes, an enquiry originating mobile terminal transmits enquiry information in an enquiry frame to the N-th layer exchange through the N-th layer base station. The exchange discriminates a kind of the enquiry frame at processing, selects at processing, a minimum cell for covering a distribution area or a minimum number of cells which can cover the distribution area from the state of geographical distribution of the enquiry destinations, fills the numbers of the base stations for forming these cells and the numbers of the exchanges for covering these base stations in the enquiry frame, and transmits this enquiry frame to the corresponding exchange. The exchange checks the numbers of the base stations of the enquiry frame and transmits the enquiry frame to the corresponding base stations. The base stations transmit the received enquiry frame directly to the mobile terminals of the destinations.
摘要:
An image fixing rotatable member and an image fixing apparatus using the rotatable member as a pressing rotatable member, having a fluorine resin tube over a rubber layer, wherein the volume resistivity of the rubber layer is lower than that of the fluorine resin tube so as to avoid charge build-up on the fluorine resin tube.
