Patent ID: 11567438

Abstract:
An image forming apparatus includes: a transporter; an image former; a reflective optical sensor; an image density adjuster; and a controller. The image former includes: a photoreceptor; a charger; an exposer; a developer; a transferor; and a fuser. The reflective optical sensor is provided opposite to the photoreceptor across a conveyance path. During image density adjustment, the controller forms a predetermined patch toner image on the photoreceptor, irradiates the patch toner image with light, and control the image density adjuster to adjust image density based on reflected light from the patch toner image. During image forming, the controller causes the reflective optical sensor to emit light on timing that a predetermined leading edge area of the recording area passes, and decides based on reflected light therefrom whether a width in the main scanning direction of a recording medium is longer than a predetermined reference length.
