Image forming apparatus

摘要

In an image forming apparatus, a controller includes a memory stores control parameters for use in adjustment to be made in at least one of a print density and a color alignment in accordance with a surrounding condition, a print-mode execution module executes a print-mode process of causing the image forming unit to perform image formation, and an adjustive test-mode execution module executes an adjustive test-mode process of causing the image forming unit to perform a test print, thereby determining a control parameter. The print-mode execution module retrieves a relevant control parameter corresponding to a current surrounding condition from the memory, if available, while it causes the adjustive test-mode execution module to execute the adjustive test-mode process, thereby determining a relevant control parameter if the relevant control parameter is not stored in the memory. The retrieved or determined relevant control parameter is applied to the image formation.

1. An image forming apparatus comprising:
an image forming unit including a photoconductor drum, a charger configured to charge the photoconductor drum, an exposure device configured to expose the photoconductor drum to light, and a developing roller configured to supply developer to the photoconductor drum; and a controller configured to control an operation of the image forming unit, wherein the controller comprises:
a memory configured to store control parameters for use in adjustment to be made in at least one of a print density and a color alignment in accordance with a surrounding condition;a print-mode execution module configured to execute a print-mode process of causing the image forming unit to perform image formation; andan adjustive test-mode execution module configured to execute an adjustive test-mode process of causing the image forming unit to perform a test print, thereby determining a control parameter, and causing the memory to store the determined control parameter associated with a specific surrounding condition under which said test print was performed, wherein the print-mode execution module is configured: (1) to retrieve a relevant control parameter corresponding to a current surrounding condition from the memory if the relevant control parameter is stored in the memory when the print-mode execution module executes a print-mode process; and (2) to cause the adjustive test-mode execution module to execute the adjustive test-mode process, thereby determining a relevant control parameter if the relevant control parameter is not stored in the memory when the print-mode execution module executes the print-mode process, whereby the retrieved or determined relevant control parameter is applied to the image formation to be performed by the image forming unit.
