摘要:
A color electrophotographic image forming apparatus includes: a drum cartridge, detachably mountable to the apparatus main assembly, for holding a drum; developing cartridges, each including a developing roller for developing an electrostatic latent image formed on the drum, demountable from the cartridge; a main assembly guide for guiding the cartridge from the main assembly; a drum cartridge guide for guiding the developing devices independently demountably from the cartridge; and a drum cartridge preventor for preventing movement of the cartridge. When the developing cartridge is demounted while drum cartridge is mounted in the main assembly, the preventor is movable between a first position preventing the cartridge from moving in a demounting direction and a second position permitting such movement. The apparatus includes a grip for facilitating demounting of the drum cartridge by facilitating a change of the preventor's position from the first position to the second position.

A photosensitive drum for use with an image forming apparatus includes a cylinder, having a photosensitive layer at its surface, to which process means is contacted; and a flange provided at a longitudinal end portion of the cylinder. The flange includes a supporting portion supporting an inner peripheral portion of the cylinder, a portion to be supported inside the cylinder by a supporting shaft for supporting the photosensitive drum, and a clearance portion which is provided in a region closer to a longitudinal end of the cylinder than the portion to be supported and which is out of contact with the supporting shaft. The portion to be supported is provided at a position that overlaps with the supporting portion with respect to a longitudinal direction of the cylinder as seen in a diameter direction of the cylinder. The clearance portion extends from the contact area to an area outside the contact area.

The present invention has an object to provide a fixing apparatus which is configured to easily facilitate to prevent a semi-melted developer on a recording medium from adhering to surfaces of upper rotary bodies and an image forming apparatus which is equipped with the fixing apparatus. This object is accomplished by configuring the fixing apparatus so that a sheet which has been subjected to a fixing treatment receives conveying forces from pinch rollers having rotating axial directions which are on a plane in parallel with a surface of the sheet and inclined at a predetermined angle &thgr; relative to rotating axial directions of a fixing roller and a press roller.

A stern shape of a displacement-type marine vessel enables reduction of the hull resistance and prevents propeller cavitation. The displacement-type marine vessel which travels in a velocity range in which the Froude number is smaller than the last hump and the stern includes knuckle lines connecting knuckle points provided on the surface of the hull, from a starting point in front of a propeller to an end point behind the propeller. A portion of the stern located inside the knuckle line in the direction of the width of the hull has a dome shape with upward curvature, and the length of the portion which has the dome shape is set to 10% or more of the entire hull length or at least the diameter of the propeller.

This invention relates to a resupplying apparatus detachably attached to an image forming apparatus body which comprise a resupplying passage connecting a sheet material passage on a downstream side of an image forming means in the image forming apparatus body with another sheet material passage on an upstream side of the image forming means. Also, the resupplying apparatus comprises switchback conveying means placed in the resupplying passage for reversing the conveyance direction of the sheet material upon reception of the sheet material from a conveyer in the image forming apparatus body, said switchback conveying means at least partially assembled in the image forming apparatus body; and resupplying means for returning the sheet material to the upstream side of the image forming means through the resupplying passage.

An image-forming apparatus is disclosed in which, using a photosensitive member and a toner, an unfixed image of the toner is formed on a transfer medium and the unfixed image on the transfer medium is fixed by a heat-and-pressure fixing means. In the image-forming apparatus, a delivery guide member, which guides the delivery of the transfer medium and is placed close to the heat and pressure fixing means, has a value of triboelectric voltage not greater than 500 V as measured by the triboelectric voltage measuring method according to JIS L1094B.
