Abstract: An image forming apparatus includes a developing device that develops a latent image by causing toner to adhere to the latent image via a toner carrier disposed opposite a latent image carrier on which the latent image is formed. The developing device includes a drive transmitter that transmits a driving force to a toner conveyor that conveys the toner, and the drive transmitter performs switching between a first operation of transmitting the driving force for conveying the toner to the toner conveyor and a second operation of vibrating a preventer that is provided in the developing device and prevents the toner from scattering.

Abstract: A system for predicting occurrence of a defective image includes: an input device configured to input image data into an image forming apparatus; and a hardware processor configured to analyze a spatial frequency of gradient distribution of an image in accordance with a size of a density irregularity specific to the image forming apparatus with respect to the input image data and to calculate a probability of a conspicuous density irregularity of the size in regard to the image formed by the image forming apparatus based on the image data with reference to an index of correlation between an analysis result and an evaluation value of the density irregularity.

Abstract: A lubricant coating device includes a photoconductor and a leveling blade that levels a lubricant applied on a surface of the photoconductor, the leveling blade configured to abut the photoconductor in a trail direction with respect to a rotational direction of the photoconductor, wherein a hardness of a tip of the leveling blade, the tip being positioned on a side that abuts the surface of the photoconductor, is higher than hardness of a non-abutting portion that does not abut the surface of the photoconductor.
