Abstract: A device diagnosis system includes an image forming apparatus, a portable terminal device, and an abnormal noise decision device. The portable terminal device collects an operating sound of the image forming apparatus, at a sound collecting position selected from a plurality of predetermined sound collecting positions relative to the image forming apparatus. The abnormal noise decision device (a) identifies a decision criterion corresponding to the sound collecting position, and (b) decides whether the operating sound contains an abnormal noise, on a basis of acoustic data of the operating sound collected, in accordance with the decision criterion identified.

Abstract: An image evaluation system includes an image forming apparatus and an information processing apparatus. The image forming apparatus prints a reference document including pattern images. The image forming apparatus prints, on the reference document, a check region including check items with respect to the image quality of the printed result. The image forming apparatus reads the printed reference document to generate reference document data. The image forming apparatus transmits the generated reference document data to the information processing apparatus. Based on the received reference document data, the information processing apparatus recognizes a check item selected in the check region.

Abstract: A development device includes a developer container, a developer bearing member, a mixing/transporting member, an opening/closing member, and a drive mechanism. The developer container contains a developer. The developer bearing member is rotatably supported by the developer container. The developer bearing member also has a surface facing an image bearing member on which an electrostatic latent image is to be formed. The developer is borne on the surface of the developer bearing member. The mixing/transporting member mixes and transports the developer in the developer container. The opening/closing member opens and closes a developer outlet for discharging an excess of the developer in the developer container. The drive mechanism drives the opening/closing member in association with driving of the developer bearing member or the mixing/transporting member to open the developer outlet.

Abstract: In an image forming apparatus, a controller allows a sound output device to output a starting sound and an ending sound at a start and end of diagnostic image formation processing, respectively, determines whether abnormal noise has occurred by identifying data ranging from the starting sound to the ending sound in an diagnostic spectrogram as a comparison target for data ranging from the starting sound to the ending sound in a normal spectrogram to match both the spectrograms in terms of width in a time-axis direction, and identifies a source of the abnormal noise by identifying the data ranging from the starting sound to the ending sound in the diagnostic spectrogram as a comparison target for data in ranging from a timing of start to a timing of end in a timing chart to match the diagnostic spectrogram with the timing chart in terms of width in the time-axis direction.

Abstract: A fixing device includes a first rotary member, a second rotary member, a support member having a connection part, an urging member, and an engaging member. The engaging member is capable of changing a state of the fixing device between a pressure applied state and a pressure reduced state using the urging member and the support member. When the nip pressure is in the pressure applied state, the engaging member changes a position of the urging member to direct the urging member longitudinally in a tangential direction to an arc that has a center coinciding with a center of rotation of the support member and that passes through the connecting portion. When the nip pressure is in the pressure reduced state, the engaging member changes the position of the urging member to direct the urging member longitudinally in a direction different from the tangential direction.

Abstract: An image forming device includes: a secondary transfer roller configured to secondarily transfer a toner image transferred to an intermediate transfer belt, to a transfer paper; separating plates; and a power supply circuit configured to apply bias voltages to the separating plates. The separating plates are configured to separate the transfer paper from the intermediate transfer belt when the bias voltages are applied to the separating plates. The separating plates include two or more separating plates installed along a direction perpendicular to the transfer paper conveying direction. The bias voltages are applied to the separating plates independently of each other depending on a toner amount distribution of the toner image transferred to the transfer paper, in the direction perpendicular to the transfer paper conveying direction.
