Title: Image forming apparatus, control method for image forming apparatus, and control program for image forming apparatus
Inventor: INOUE KEISUKE
IPC: G03G15/00
Filed: 2010-01-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that consumes less power and prevents nonuniform charging.  <P>SOLUTION: The image forming apparatus charges a photoreceptor by means of a charger and forms an image by an electrophotographic system. The image forming apparatus controls a charger current caused to flow in the charger, according to a humidity change rate. The CPU of the image forming apparatus detects a humidity at a predetermined detecting time, and detects a humidity change (S101 and S103). A CPU 21 determines whether the humidity change is greater than a predetermined threshold. If it is greater, control for increasing a charger current is performed to thereby prevent nonuniform charging (S105 and S107). When a stop cancellation condition is satisfied due to, for example, an elapse of a predetermined time after a charger current is increased, the CPU 21 cancels stopping the control of the charger current, and controls the charger current corresponding to a humidity change again. This increases the charger current only for a required period.  <P>COPYRIGHT: (C)2011,JPO&INPIT
