To provide an image printing apparatus, a reading apparatus, an image printing method, and a printing medium conveyance method, with which occurrence of image unevenness or streaks due to conveyance is prevented, an image sensor reads an image area, so as to detect a conveyance amount of a printing medium. Further, the conveyance amount is corrected according to a distance between the image sensor and the printing medium, which is detected by a height detection sensor, so as to obtain a highly accurate conveyance amount.

A recording apparatus includes a lower unit having a recording section configured to perform recording on a medium, and an upper unit disposed on the lower unit, the upper unit including a reading section configured to read an image of the document, in which the lower unit includes a medium discharge section configured to discharge the medium toward the rear of the apparatus, and a medium receiving section disposed on the apparatus rear side with respect to the medium discharge section, the medium receiving section being configured to receive the medium discharged, and the upper unit is shorter than the lower unit in the apparatus front-rear direction and the upper unit is closer to the apparatus front with respect to the lower unit such that an end portion of the medium receiving section in the medium discharging direction is exposed at the rear of the upper unit.

An example system includes a primary device and at least one auxiliary device connected in series with the primary device. The auxiliary device has an identifier indicative of a position of the auxiliary device in the series. The identifier is based on a resistance value associated with the auxiliary device, the resistance value being based at least in part on an upstream device in the series.

An image forming apparatus includes: an image carrier in which a latent image is formed; a developing device that transfers toner to the latent image from a developing member opposed to the image carrier, and develops the latent image; a development power supply that applies a development voltage across the image carrier and the developing member; a period detector that detects periodic information on the developing member and the image carrier in a circumferential direction; and a corrector that corrects the development voltage or an exposure amount of the latent image based on the periodic information detected by the period detector. At least one of the developing device and the development power supply is set so that a supply rate of charge of the toner to the latent image in a solid area of an image reaches 80% or higher.

A device including a replaceable component, in which the component is not electrically connected to the device and includes a component-side storage, a component-side transmitter/receiver, a component-side hardware processor, and a component-side power generator, the device includes a main-body side storage, a counter which counts up the consumption degree of the component stored in the main-body storage, a main-body side transmitter/receiver, a main-body side hardware processor, a main-body side power generator, and a detector which detects attachment and detachment, the main-body side hardware processor causes the main-body side transmitter/receiver to transmit the specific identification information of the component and the consumption degree of the component when detachment is detected, and the component-side hardware processor rewrites the information in the component-side storage on the basis of the specific identification information of the component and the consumption degree of the component.

An image forming apparatus includes a photosensitive member; an exposure portion configured to expose the photosensitive member to light depending on image information to form a latent image on the photosensitive member; a developing portion configured to develop the latent image into a toner image with toner; and a transfer portion configured to transfer the toner image from the photosensitive member onto a recording material. The image forming apparatus changes a surface movement speed of the photosensitive member at timing prior to predetermined timing, when a moving speed of a recording material at the transfer portion changes, by a predetermined time.

A transfer transporting device includes multiple rollers, an endless belt, a pair of support members, and a pair of unloading members. The rollers include a driving roller and a driven roller. The driving roller is disposed closer to an image carrier that has a toner image formed thereon and that holds the toner image. The driven roller is disposed apart from the driving roller downstream in a sheet transport direction. The endless belt is wound around the rollers. The pair of support members each have an outer wall surface facing a side end surface of the belt. The pair of support members are disposed on both sides of the belt to rotatably support a rotation shaft protruding from side end surfaces of the driving roller. The pair of unloading members are interposed between the outer wall surfaces of the pair of support members and the side end surfaces of the driving roller. The pair of unloading members each reduce, while being in contact with a corresponding one of the side end surfaces of the belt, a driving load on the driving roller further than in a case where the side end surfaces of the belt come into direct contact with the outer wall surfaces. The image carrier and the belt hold therebetween a sheet transported thereto to transfer the toner image on the image carrier to the sheet, and transport the sheet downstream.
