摘要： An image forming apparatus allowing an image carrier included therein to be desirably cleaned is disclosed. A developing device uses a developing liquid consisting of a carrier liquid and toner dispersed therein. A toner image produced by the developing device is transferred to an intermediate image transfer belt. A cleaning roller cleans the surface of the intermediate image transfer belt after the transfer of the toner image to a paper sheet or similar recording medium. A liquid cleaning device feeds a cleaning liquid to the cleaning roller. The developing liquid may be replaced with a dry developer containing at least powdery toner.

摘要： A tandem image forming device for an image forming apparatus of the present invention includes a plurality of image forming means arranged side by side along an intermediate image transfer belt. The image forming means each include a developing device and a cleaning device arranged around an image carrier. One of nearby image forming means has its cleaning device positioned above the developing device of the other image forming means, e.g., an agitating section forming part of the image forming means. This configuration insures smooth circulation of a developer and therefore obviates an irregular developer distribution while reducing the overall size of the image forming device.

摘要： A toner image transfer method for transferring a toner image formed on a latent image carrier onto a transfer image carrier. A reference running speed of the latent image carrier VA and a reference running speed of the transfer image carrier VB are set substantially as VA=VB=V. A relative speed ΔV between the latent image carrier and the transfer image carrier is changed in vibration at a high speed to positive and negative sides around the reference running speed V, thereby to carry out an image transfer.

摘要： An image forming apparatus of the present invention includes at least one rotatable image carrier, an image forming device for forming different images on the image carriers, a first image transferring device for transferring the images from the image carriers to a first image transfer body driven to move via a first image transfer position where it faces the image carriers, and a second image transferring device for transferring the resulting composite image from the first image transfer body to a second image transfer body driven to move via a second image transfer position where it faces the first image transfer body. The moving speed of each image carrier is equal to the moving speed of the second image transfer body. A period of time necessary for the surface of the first image transfer body to move from the first image transfer position to the second image transfer position is a natural number multiple of the period of speed variation occurring on the above surface.

摘要： An image forming apparatus includes an image carrying member, a development unit, a first driving unit, a second driving unit, and a cleaning blade. The image carrying member forms a latent image thereon. The development unit develops the latent image formed on the image carrying member. The first driving unit drives the image carrying member. The second driving unit drives the development unit. The cleaning blade, contactable against the image carrying member, removes materials including toner remaining on the image carrying member. When an agent-empty development unit is filled with a developing agent, the second driving unit is activated to start a driving of the development unit, and the first driving unit is activated to start a driving of the image carrying member after starting a developing agent filling operation to the development unit.
