An image forming apparatus includes image bearers, motors, a reference position detector, and processing circuitry. The circuitry senses a density of a toner image on each bearer; forms an image pattern and senses, based on a detection result of the detector and a sensing result of the density, density unevenness in a rotation cycle and a phase of the density unevenness with respect to a rotational position reference of each bearer; calculates a target phase based on the phase sensed; calculates a relative phase difference based on a rotational position and the target phase of each bearer; selects, as a reference image bearer, an image bearer having a minimum phase correction value, based on a calculation result of the difference; and controls the rotational position of each of the other image bearers with respect to the reference image bearer to the phase correction value, with the motors being driven.

An electrophotographic photoreceptor includes a conductive support in which (i) a recessed portion having an opening diameter of greater than 400 μm and (ii) a recessed portion having an opening diameter of from 100 μm to 400 μm and a ratio of a depth to an opening diameter of greater than 0.12 are not present on an outer peripheral surface, wherein even in a case where a first recessed portion having an opening diameter of from 100 μm to 400 μm and a ratio of a depth to an opening diameter of 0.12 or less is present on the outer peripheral surface of the conductive support and a second recessed portion on which the first recessed portion is reflected is present on the outer peripheral surface of an outermost layer, a ratio of a depth to an opening diameter of the second recessed portion is not greater than 0.030.

If a timing of outputting magnification correction data for first image data to form first electrostatic latent image for an (n+1)th print medium overlaps a timing of outputting magnification correction data for second image data to form an electrostatic latent image for an nth print medium having a size smaller than the (n+1)th print medium in a conveyance direction of the print medium, a CPU outputs the magnification correction data for the second image data to form the second electrostatic latent image for the nth print medium before the magnification correction data for the first image data to form the first electrostatic latent image for the (n+1)th print medium is output and outputs the magnification correction data for the (n+1)th print medium after a magnification correction process performed by a second data processing unit based on the magnification correction data for the nth print medium is completed.

A drum supporting member, which is usable with an image forming apparatus, includes a photosensitive drum and a mounting portion for detachably mounting a developing cartridge. The drum mounting portion also includes a contacting member contactable with the developing cartridge, with contacting member being movable between a first position and a second position. When the contacting member is in the first position, the contacting member contacts the developing cartridge with a developing roller of the developing cartridge being placed in a third position contacting the photosensitive drum. When the contacting member is in the second position, the contacting member contacts the developing cartridge with the developing cartridge being placed in a fourth position in which the developing cartridge is dismountable from the drum supporting member. The drum supporting member further includes an elastic member configured to urge the contacting member against movement of the developing cartridge in a direction from the fourth position to the third position.

An image forming apparatus is described. An image forming apparatus may include an image forming apparatus body and a tandem type photosensitive unit slidable with respect to the body, wherein the unit includes: a frame; a plurality of photosensitive bodies; a plurality of developer cartridges, including developer carriers, detachably mountable on the frame; and a pressing portion provided on the frame for pressing each of the cartridges so that the developer carrier thereof is directed toward the corresponding photosensitive body, each of the cartridges is pivoted to be movable to an imaging position pressed by the pressing portion and a detached position released from the pressing by the pressing portion, and the body is provided with an abutting portion abutting the cartridge located on the detached position thereby pivoting the cartridge and moving the same to the imaging position when the unit is mounted on the body.

A system in an embodiment includes an image forming apparatus, an erasing apparatus, a first apparatus, and a display unit. The image forming apparatus forms an image on a sheet using a decolorable color material. The erasing apparatus decolorizes an image. The first apparatus computes, from a reduction in the number of sheets achieved by a setting for image formation in the image forming apparatus, the amount of a reduction in environmental burdens achieved by use of the image forming apparatus and computes, from the number of sheets erased by the erasing apparatus, the amount of a reduction in environmental burdens achieved by use of the erasing apparatus. The display unit simultaneously displays the amount of the reduction in environmental burdens achieved by the image forming apparatus and the amount of the reduction in environmental burdens achieved by the erasing apparatus.

An image forming apparatus includes a chassis having an opening, a cover, photosensitive members, an intermediate transfer belt, a primary-transfer member, a secondary-transfer roller, a cleaner device, an external-sheet inlet, a waste toner container, a connector, and a conveying roller, which is arranged within the feeding path to feed the recording sheet inserted through the external-sheet inlet in the feeding path. The conveying roller is mounted on the waste toner container and removable from the chassis along with the waste toner container.

A social networking system user may request physical prints of digital photographs stored in connection with the user's user profile on the social networking system. The physical prints are generated by a photograph developer, such as a retail store, and retrieved by the user. The user may request the physical prints from an application executing on a user device that allows the user to identify social context information associated with a digital photograph for inclusion on the physical print. The social networking system may notify users connected to the user and/or to the digital image of the physical print generation.

The printed board includes a slit portion and a first conductive member that is provided straddling the slit portion. In a state in which the printed board is attached to an apparatus to which one end of a second conductive member having an elastic force is connected, another end of the second conductive member contacts the first conductive member, and the another end of the second conductive member passes through the slit portion.

A belt conveyance apparatus includes a plurality of support rollers, an endless belt, a regulation portion configured to regulate a shift of the endless belt in a width direction, a regulation receiving member configured to contact the regulation portion to receive a regulation force by the regulation portion, and support members disposed on an upstream side, in a conveyance direction of the endless belt, of the support rollers provided with the regulation portion to oppose each other on an inner peripheral surface side and an outer peripheral surface side of the end portion side of the endless belt in the width direction, and configured to regulate a position of the regulation receiving member when the regulation receiving member enters a contact portion with the regulation portion.
