摘要:
A color image forming apparatus having a revolving type developing unit detachably installed therein. The revolving type developing unit includes a plurality of different color developing devices each having a developing roller therein. Each of the developing rollers is movably mounted on the developing device so that a gap between each of the developing rollers and a periphery of a photoconductive drum which is to be formed when the revolving type developing unit is set in the color image forming apparatus is enabled to be adjusted.

An image forming apparatus includes an image bearing member, a developing device to develop a latent image on a surface of the image bearing member, a developer bearing member including a magnet therein, which bears developer on a surface thereof by a magnetic force of the magnet and carries the developer towards a developing position facing the image bearing member by being rotated, a limiting member that is placed facing the developer bearing member so as to limit a thickness of a layer of the developer borne on the developer bearing member, and a developing device casing. The limiting member is provided with a magnetizable member having a protruding portion protruding toward the developer bearing member at a part that does not face the magnet and a recessed part at a part that faces the magnet, in which the magnetizable member is disposed upstream of the limiting member in a developer conveying direction of the developer bearing member and is placed such that the protruding portions are nearer to the surface of the developing roller than the limiting member and the recessed part is more distant from the surface of the developing roller than the limiting member. The limiting member is made of a non-magnetizable material.

An algin-containing food or beverage comprises a low-molecular weight algin which has a weight-average molecular weight in the range of 10,000-900,000 and still functions as a dietary fiber and has beneficial effects on the health. The algin can be prepared by subjecting a high-molecular weight naturally occurring algin or its derivative to heat treatment at a temperature of 100.degree.-200.degree. C. under pressure.

An automatic transmission includes a fluid-pressure differential cylinder for select operation of the transmission and a fluid-pressure differential cylinder for shift operation of the transmission, each of the differential cylinders being built up into one block and joined with the mating differential cylinder with intake and discharge holes in one block held in communication with intake and discharge holes, respectively, in the other block. A piston rod of each of the differential cylinders has an annular groove and a cylinder block is provided with a locking member engageable with the groove to provide a reference position for the piston rod.

An automatic gear change device includes a first actuator operation control circuit for controlling the operation of a first actuator, a second actuator operation control circuit for controlling the operation of a second actuator, and a main control circuit for controlling the operation of the first and second actuator operation control circuits. The device further includes a communication line interconnecting the first and second actuator operation control circuits to thereby enable data transmission/reception between each operation control circuit and the main control circuit through the other actuator operation control circuit and the communication line.

A mobile phone includes a first display 11, a second display 21 arranged juxtaposed with the first display 11, and touch panels 12, 22 disposed on the displays 11, 21 for detecting that an icon has been dragged. In response to user's dragging an icon, a CPU 100 executes a reduced screen display processing of reducing in size a display screen of each of the displays 11, 21 to display the reduced display screens on the display on which the dragging operation is being performed. When the dragging operation has finished, the reduced display screens are returned to the display screens having the original size. Then, the CPU 100 displays the icon at a position, on the display screen having the original size, corresponding to the position of the icon on the reduced display screen at a time when the dragging operation has finished.

A cleaning apparatus is for removing a toner from a surface of an endless belt. The cleaning apparatus includes a blade, a blade holding structure, and an abutment maintaining structure. The blade abuts on the endless belt that is supported on a tension roller. The blade holding structure holds the blade with its rotation restricted, in a movable manner in the direction of motion adjustment to adjust tension on the endless belt, and causes the blade to abut on a winding area of the endless belt with respect to the tension roller. The abutment maintaining structure allows the blade to follow up movement of the tension roller to thereby maintain abutment of the blade on the endless belt.
摘要:
An image forming apparatus including a fixing roller and a pressure roller in which a temperature of the fixing roller and/or the pressure roller is changed differently depending on an operation mode. In particular, the temperature of the fixing roller and/or pressure roller of an operation of a non-full color mode is changed to a lesser degree than that of a full color mode operation. In another embodiment of the present invention, the temperature of the fixing roller is set to an appropriate value when an environment temperature sensor is not working properly, to produce high quality images. In yet another embodiment according to the present invention, the temperature of the fixing roller is set to an appropriate value, when an image forming apparatus is turned off for a predetermined period of time, to produce high quality images.
摘要:
In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, an unstabilizing agent is provided to the image holding member. An attaching state between the image forming substance and the image holding member stably attaching the image forming substance on a surface thereof is changed to an unstable state by the unstabilizing agent. The image forming substance is separated and removed from the image holding member by making a separating member come in close contact with the image forming substance on the image holding member having the provided unstabilizing agent. A processing situation mark showing a processing situation of removal of the image forming substance is formed in the image holding member. The processing situation mark can be removed from the image holding member by the image forming substance removing processing.
