Abstract: A reading apparatus includes an image reader for reading a sheet original positioned at a reading position and an automatic original conveyor for supplying the sheet original onto the reading position, wherein the sheet original can be read through an image flow reading mode while the sheet original is being conveyed by the automatic original conveyor by fixing the image reader at any position. The apparatus also has a convey path for directing the sheet original to the reading position, and a controller for initiating conveyance of the sheet original waiting at a predetermined position in the convey path in response to a flow reading mode start signal during the image flow reading mode and for initiating the image flow reading mode by outputting an image tip signal when a tip end of the sheet original reaches a flow reading image tip position.

Abstract: Disclosed is an image forming apparatus with an image forming device for forming an unfixed image on a recording material and; first and second rotatable members for forming a nip for conveying the recording material supporting the unfixed image. The second rotatable member has its maximum diameters between a longitudinal center and one longitudinal end and between the center and the other longitudinal end thereof.

Abstract: An image forming apparatus includes an image bearing member, image forming station for forming a latent image on the image bearing member, a conveying passage extending toward the image bearing member to guide a developing device, a first moving mechanism for engaging with the developing device in the conveying passage and moving it in a substantially horizontal plane, wherein the image bearing member, the latent image forming station, the conveying passage and the first moving mechanism are provided in a main body of the image forming apparatus, a device for accommodating a plurality of developing devices.
