An image forming apparatus includes a body, a developer recovery container, a detecting section, a power supply, a detection object part, a pair of wires, a conducting section, a drive section, and a determining section. The determining section determines the developer recovery container to have been used in a case where the developer is determined to be not present in the detection object part on the basis of information from the detecting section, and in a case where the developer is determined to be present in the detection object part, checks the information from the detecting section again after driving the drive section, and determines the recovery container to have not been used when the developer is determined to be not present in the detection object part and determines the recovery container to have been used when the developer is determined to be present in the detection object part.

Image forming apparatus, image forming system, and computer readable medium

An image forming apparatus includes: an image forming apparatus body, a photosensitive member, an intermediate transfer belt, and a developing device placed on a side opposite to the intermediate transfer belt across the photosensitive member and provided with a detachable toner cartridge. The intermediate transfer belt is disposed such that a distance between ends in a height direction is longer than a distance between ends in an anteroposterior direction. At least a part of the photosensitive member is placed between the anteroposterior ends of the intermediate transfer belt. The image forming apparatus body includes an openable section at an upper face side or a front face side thereof to allow the toner cartridge to be attached and detached therethrough and to allow a jam to be fixed therethrough.

An IOT controller of an image formation device is provided with an NvRAM. Correction coefficients relating to various parameters, which are specified for each of paper types in advance, are stored in the NvRAM. The NvRAM is provided with a user setting region, and when it is desired to form an image at an unusual paper, parameters of this paper can be inputted by operation of a control panel. When image formation is to be implemented, the IOT controller, after selection of a paper type at the control panel, reads out correction coefficients of the parameters relating to the selected paper type from the NvRAM, implements transfer processing in accordance with these correction coefficients, and forms a high-quality image.

Image formation device and sheet material selection device

An image formation apparatus including a photoreceptor, a charger having a charger member for charging the photoreceptor, a latent image write unit for writing an electrostatic latent image onto the photoreceptor charged by the charger, and a developing device having a developer support with a magnetic field production member, for rendering visible the electrostatic latent image written by the latent image write unit with a developer. Further, the charging member of the charger is disposed under effect of a magnetic field produced by the magnetic field production member of the developing device, and the charging member is made of a nonmagnetic material.

In an image recording apparatus, the surface of an image carrier is formed of a material having a high affinity to particulates the particle size of which is smaller than toner and the surfaces of which have been treated to be hydrophobic, so that a layer of the particulates treated to be hydrophobic is retained on the surface of the image carrier.
