Abstract: An image forming apparatus includes a developing device for developing a latent image formed on an image bearing member into a developer image; a transferring device for transferring the developer image from the image bearing member onto a transfer material; a temperature detecting sensor in a main assembly of the image forming apparatus, for detecting a temperature; and a controller for controlling a forced consumption operation in which toner is forcedly consumed by the developing device without transferring the developer image from the image bearing member onto the transfer material. The controller is capable of executing the forced consumption operation when toner consumption is below a predetermined threshold. The predetermined threshold is higher with higher temperature.

Abstract: An image forming apparatus includes a developing device for developing a latent image formed on an image bearing member into a developer image; a transferring device for transferring the developer image from the image bearing member onto a transfer material; a temperature detecting device, disposed in a main assembly of the image forming apparatus, for detecting a temperature; and a controller for controlling a forced consumption operation in which toner is forcedly consumed by the developing device without transferring the developer image from the image bearing member onto the transfer material. The controller is capable of controlling the forced consumption operation so that a frequency of the forced consumption operation or an amount of toner consumption per one forced consumption operation when the temperature detected by the temperature detecting device is higher than a predetermined temperature is more than that when the temperature detected by the temperature detecting device is lower than the predetermined temperature.

Abstract: An image forming apparatus capable of forming an image with a color toner and a transparent toner does not always form an image using the transparent toner. Under the circumstance where the image in which the transparent toner is more easily deteriorated than the color toner is output, if the deteriorated transparent toner is frequently discharged, the productivity may be lowered. Thus, when an amount of the transparent toner applied to the recording material that is acquired by an acquisition device is less than a predetermined amount, the transparent toner in the amount more than that acquired by the acquisition device is applied to the recording material.
