Abstract: A developing device includes: an image bearing member; a plurality of developing rollers each supplying toner to the image bearing member, and developing an electrostatic latent image on the image bearing member into a toner image; and a hardware processor analyzing values representing density fluctuations during the toner being supplied from the developing rollers to the image bearing member, for the respective developing rollers, and correcting a control value for an image density of at least one developing roller among the developing rollers based on an result of the analyzing so as to eliminate the density fluctuations, in consideration of an effect caused at the developing roller on a downstream side in a rotational direction of the image bearing member by correcting the control value for the image density of the developing roller on an upstream side.

Abstract: An image forming apparatus that forms an image on a transfer material in an image forming mode, includes: a photoreceptor rotatable in a predetermined rotation direction; a developer that forms a toner image on the photoreceptor using a two-component developing agent including toner and a carrier; a transferor that transfers the toner image on the photoreceptor onto the transfer material; a carrier collector that applies an electric field corresponding to a collecting bias to a carrier adhering to the photoreceptor to collect the carrier; a carrier detector that detects a carrier remaining on the photoreceptor after collecting the carrier by the carrier collector; and a hardware processor that sets the collecting bias in the image forming mode on the basis of the amount of carriers detected by the carrier detector when a carrier adhesion detecting mode for forcibly causing a carrier to adhere to the photoreceptor is executed.

Abstract: A wearable computer includes a computer, a display unit, first and second casings, temples, a holding member and an adjustment mechanism. The second casing houses the computer. The temples are respectively connected to one end and, through a connection member, the other end of the first casing in a longitudinal direction. The holding member extends downward from the connection member and holds a nose pad and a translucent member. The display unit extends downward from the first casing and to outside of an installation space of the translucent member to face one eye of a wearer. The adjustment mechanism adjusts a relative position of the display unit and the nose pad. The wearable computer is wearable with the first casing being held above the one eye by the temples, the connection member and the nose pad.
