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.

Claim (Index 5):
The image forming apparatus according to  claim 4 ,\n wherein the carrier detector comprises: an adhesive roller that abuts against the photoreceptor during execution of the carrier adhesion mode and rotates in accordance with the rotation of the photoreceptor to adsorb the carrier on the photoreceptor; and a detection sensor that detects the carrier adhering to the adhesive roller, the hardware processor measures a cumulative amount of carriers adhering to the adhesive roller in a cumulative manner when a value of a condition related to the collecting bias is continuously varied, and the hardware processor sets, as the collecting bias, a collecting bias with which the amount of change in the cumulative amount of carriers before and after varying the value of the condition is the minimum.
