A reaction cartridge comprises a first liquid reservoir having a first aperture exposed to the atmosphere and a second aperture, a first flow channel connected to the first liquid reservoir, a reaction chamber communicating with the first liquid reservoir by way of the first flow channel, a second flow channel connected to the reaction chamber and a third aperture connected to the second flow channel and exposed to the atmosphere. A probe carrier is arranged in the reaction chamber and externally supplied liquid is stored in the first liquid reservoir. The reaction cartridge is adapted to move liquid between the liquid reservoir and the reaction chamber by increasing or reducing the pressure at the third aperture.

A sheet member feeding device comprises a first gear transmitting a driving force to a feeding roller for intermittently feeding a sheet member per a predetermined feeding amount, a second gear having a first mark and a second mark representative of a maximum eccentric position and a minimum eccentric position along a radial direction relative to a predetermined concentric circle in a tooth space, in opposition to each other and directly or indirectly transmitting a driving force to the first gear, a third gear directly or indirectly transmitting driving force from driving means to the second gear, detecting means for detecting the first mark and the second mark in the second gear and transmitting a detection output, and a control portion operating the driving means for performing operation for rotating the second gear through 180&deg; between the first mark and the second mark with respect to feeding for a feeding amount of the sheet member for one time, on the basis of the detection output from the detecting means.

Sheet member feeding device, recording apparatus employing the same and image pick-up apparatus with recording mechanism

An image forming apparatus includes a plurality of image bearing members; image forming means for forming images of different colors on the image bearing members, respectively; a transfer material conveyer belt for carrying a transfer material; a driving roller for transmitting a driving force to the transfer material conveyer belt; wherein the images of different colors formed on the image bearing members are sequentially transferred in an overlying manner onto the transfer material carried on the transfer material conveyer belt; storing means for storing information on thicknesses of the transfer material conveyer belt at different positions in a movement direction thereof; detecting means for detecting a predetermined position of the transfer material conveyer belt; and control means for controlling timing of start of image formation for each of the image bearing members by associated one of the image forming means on the basis of the information stored in the storing means and a result of detection by the detecting means.

Belt, image forming apparatus which employs belt, belt replacing method and belt control program

An image forming apparatus includes a transfer material carrying belt for carrying a transfer material; a support for supporting the transfer material carrying belt at a side opposite from a side carrying the transfer material; an image forming unit for forming an image on a transfer material carried on the transfer material carrying belt; wherein the support is disposed at a position out of a portion where the carrying belt constitutes a carrying surface for the transfer material, and includes a driving roller for driving the transfer material carrying belt and a follower roller which is disposed at a position where the transfer material is separated from the transfer material carrying belt after completion of image formation of the image forming unit.

Image forming apparatus

The present invention provides an image forming apparatus comprises an image bearing member for bearing a toner image, a rotatable transfer material bearing member for bearing a transfer material, a convey means for conveying the transfer material to the transfer material bearing member, the convey means having a transfer material conveying speed faster than a rotational speed of the transfer material bearing member, and an urging means for urging the transfer material against the transfer material bearing member at an urging position, and wherein the toner image on the image bearing member is transferred onto the transfer material at a transfer position where the transfer material is urged against the transfer material bearing member by the urging means and born on the transfer material bearing member, and, when the transfer material is pulled by a force greater than 10 N along a transfer material conveying direction in a condition that the transfer material is urged against the transfer material bearing member by the urging means, the transfer material starts to be slipped with respect to the transfer material bearing member.

The impact sound when a sheet member forms a loop is reduced so as to make the apparatus less noisy. A speed control device is provided for making the transport speed when the sheet member is made to hit a first transport device by a second transport device relatively slower than that of the first transport device. By changing the amount of transport of the first transport device along the width of the sheet member at right angles to the transport direction of the sheet member, the loop is formed successively along the width of the sheet member.

Sheet transport apparatus and image forming apparatus

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. The accommodating device is mounted to the main body, the accommodating device includes, a second moving mechanism for moving the developing device opposed to the conveying passage into the conveying passage in a substantially horizontal plane and an accommodating case having partition stages arranged substantially vertically for accommodating plural developing devices and movable together with the developing devices accommodated therein, and a driver for transmitting a driving force selectively to the first driving mechanism, the second driving mechanism and the accommodating case.
