摘要： A developing device includes a development unit, a developer amount detector, an accuracy requirement determiner, and a detection count setting unit. The development unit includes a developer container configured to store a developer. The development unit is configured to supply the developer from the developer container to a latent image bearer, on which an electrostatic latent image is to be formed according to image data, to form a developer image. The developer amount detector is configured to detect a developer amount in the toner container of the development unit in every detection period. The accuracy requirement determiner is configured to a determine accuracy requirement required as a detection accuracy of the developer amount by the developer amount detector. The detection count setting unit is configured to set a number of times of detection of the developer amount by the developer amount detector based on the accuracy requirement.

摘要： An image forming apparatus includes an image forming unit, a first detector including a first light emitting device, a first mixed-light receiving device and a first diffuse reflection light receiving device, a second detector including a second light emitting device and a second mixed-light receiving device, and a concentration correction unit. The first mixed-light receiving device detects a mixed light including regular and diffuse reflection light reflected from a transport member. The first diffuse reflection light receiving device detects the diffuse reflection light. The second mixed-light receiving device detects the mixed light. The concentration correction unit conducts concentration correction using detection results of the first and second detectors. A first correction pattern reflecting the regular and diffuse reflection light and detectable by the first detector and a second correction pattern reflecting only the regular reflection light and detectable by the second detector are formed different positions on the transport member.
