An electrophotographic photoconductor having at least a photoconductive layer on an electrically conductive support, in which a surface layer of the photoconductive layer can be obtained by curing at least a free-radical-polymerizable monomer having no charge transporting structure, represented by general formula (A)and a one-functional free-radical-polymerizable compound having a charge transporting structure, wherein R71, R72, R73, R74, R75, and R76 are described in the specification.

An image forming method is performed by an image forming apparatus having a head mounting a plurality of writing units that form an image on a recording medium. The writing units are aligned in a sub-scanning direction perpendicular to a main-scanning direction. A part of the image is formed on the recording medium by the writing units, the part of the image forming a line extending in the main-scanning direction. The step of forming a part of the image is repeated while shifting the writing units in the sub-scanning direction by a predetermined amount of shift. The amount of shift of the wiring units is varied so that an amount of misalignment in a connecting portion between the parts of the image on the recording medium is reduced.

The present invention provides an electrophotographic photoconductor which includes at least a photosensitive layer and a surface protective layer over a support, wherein the surface protective layer contains a filler, a charge transporting material and a specific compound; and the photosensitive layer contains at least a charge transporting material; the charge transporting material contained in the photosensitive layer has an oxidation potential lower than the oxidation potential of the charge transporting material contained in the surface protective layer and is a specific compound.

A fixing device has a magnetic field generator; an electric power supplier for electric power supply to the magnetic field generator; electric power controller for controlling an electric power value to be supplied by the electric power supplier; a fixing member, disposed in the magnetic field, having an electroconductive layer which generates heat by eddy current generated by the magnetic field; a temperature detecting member for detecting a temperature of the fixing member; a discriminator for discriminating whether the apparatus is in order by comparing a detected temperature to a reference temperature in a period from a start of heating the fixing member to arrival at a predetermined temperature; and a reference temperature changer for changing the reference temperature on the basis of the supplied electric power value upon the electric power controller changing the electric power value.

An image forming apparatus includes a developing device for developing an electrostatic latent image, formed on an image-bearing member, with toner; a developer supply container which contains developer containing toner and a carrier and is detachably mountable to a main assembly of the image forming apparatus; developer supply means for supplying the developer contained in the developer supply container to the developing-device; and developer discharge means for permitting discharge of the developer in the developing device to the outside of the developing device. To the image forming apparatus, one of plural kinds of developer supply containers containing developers having different carrier ratios in the developers is selectively mountable. The image forming apparatus further comprises notification means for providing notification of the kind of the developer supply container to be selected on the basis of information on deterioration of the carrier when the developer supply container is replaced.

An image information control method and apparatus, the apparatus includes a receiving unit configured to receive bit map image data sent from an information process unit, and an accumulating unit configured to accumulate the image data received from the information process unit line by line. A blocked unit is configured to group a plurality of lines of the image data into a predetermined size block of image data. A converting unit is configured to convert the block of image data into a language command corresponding to the image forming apparatus and including the block of image data, and a sending unit is configured to send the language command to the image forming apparatus.

An optical image capturing system, from an object side to an image side, comprises a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element. The first lens element has a positive refractive power and may have a convex object-side surface. The second through fifth lens elements has a refractive power and the object-side and image-side surfaces of these lens elements are aspheric. The sixth lens element has a negative refractive power and may have a concave image-side surface. The object-side surface and the image-side surface of the sixth lens element are aspheric, and at least one of the two surfaces has inflection points. When specific conditions are satisfied, the optical image capturing system may has a large aperture value and a better optical path adjusting ability to acquire better imaging quality.
